Regular measurement and meticulous control are the basis of all areas of construction. If an ideal result is needed in finishing or renovation, marking and checking the geometry of the structures must be carried out. A normal owner will not hang a shelf or install washing machine without measuring and control manipulations. They are carried out using building levels used to maintain horizontal and vertical directions. These are devices and devices that vary in complexity, cost, and purpose. For the home handyman you should know which building level is better, what will be useful or may not be needed on the farm.

The ancestors of building levels were a spirit level and a plumb line, used by builders for marking and control since ancient times. A plumb line is used to determine verticals, and a spirit level - horizontals.

The principle of operation of old simple devices is closely related to the law universal gravity. Most main element The simplest devices are a heavy steel blank with a cone-shaped tip. Under the influence of gravity metal part steadily strives downward, repeating the vertical line without the slightest error. Actually, the blank is a plumb line that is simply hung on a cord or fishing line if it is necessary to find or check the vertical direction.

In a spirit level, a plumb line is attached to the top of an equilateral triangle or to the highest point of the structure, shaped like an inverted letter T. Its own weight causes the blank to rush down, thereby clearly marking the vertical line. The device is applied with its base to the surface being tested. If the plumb line of the spirit level is not located exactly in the middle, i.e. does not repeat the central axis, then the surface cannot be considered horizontal.,

All types of building levels used today in construction perform similar functions. They are used for marking structures before pouring screed, leveling and plastering walls, and before installing plasterboard and suspended ceilings. Marking and checking devices are necessary when producing plumbing and window systems.

By functional purpose Representatives of the family of building levels are divided into two groups:

• Devices used for control. With their help, they check the quality of masonry, the horizontal and verticality of constructed surfaces, mounted systems, communications, and devices. The control group includes bubble building levels, often called spirit levels after their immediate predecessors.
• Devices used for marking. With their help, the position of points relative to horizontals and verticals is determined, and the contours of the created surfaces are drawn. This group includes the simplest water levels, plumb lines, and a more complex and high-precision category - laser devices.

There is no universal building level. For example, in marking, the bubble type is a very weak assistant, although a number of models have rulers with a millimeter scale. Its purpose is to display deviations from the horizontal. There is only one working edge, the other three are auxiliary: there is no point in applying them to any surfaces.

A primitive plumb line can be used for both layout and control, but only for vertical lines. It is best to mark the site with a laser level. True, the cost makes you think about the advisability of purchasing an expensive device for a single job.

An antediluvian water level is indispensable if you need to mark points at the same height in rooms separated by partitions. Before purchasing these devices and accessories, you should think carefully about the intensity of use and the rationality of costs. You need to weigh what tools you need to purchase and what is cheaper to rent.

In any case, you need to know exactly how to choose a building level and clearly understand the scope of its application.

Bubble building levels

In the name of a simple control device, in addition to the “bubble” definition, “alcohol” or “oil” can equally appear. Depending on the shape of the body, people call them “box-shaped” or “rail-shaped”. It is a bar or rail with built-in ampoules filled mainly with liquid and partly with air.

The body is most often metal, less often plastic, but outdated wooden versions are also found. Among the body materials, metal is the priority, because... polymers are not heavy enough and resistant to deformation, and wood products require increased attention, regular monitoring of readings and scrupulous care.

Regardless of the name, the operating principle of bubble levels is the same. It is based on the difference specific gravity liquids and gases, as well as the inability of substances with different states of aggregation to mix. Simply put, no matter what position the building level takes, a light air bubble will invariably end up at the top of a vessel slightly curved in the same direction. If it is installed exactly in the middle, then the surface is perfectly horizontal.

The volume of the bubble does not change; this is prevented by the hermetically sealed ampoule-flask. It will not disintegrate into several components, because the liquid will constantly push the air upward and group its scattered molecules into a single formation. To make sure, shake firmly closed with a lid a jar of water. The small bubbles that appear in it will soon disappear, and the distance between the lid and the surface of the liquid will remain the same.

Classification by functional purpose

The number of built-in flasks determines the functionality of the building-level model, because the devices:

• With one ampoule in the center of the working edge to search for deviations in the horizontal direction;
• With two ampoules: a central flask for checking horizontal lines and a side flask for checking vertical planes and lines;
• With three ampoules, two of which, by analogy, are designed to check verticals and horizontals, and the third is used to control inclined lines and planes.

The third variety with three control flasks is universal. However, if the level is purchased only in order to properly fill the screed or, in the third control device there is no reasoned need. It is in demand mainly in the construction of roofs and in the construction of stairs.

The sealed flask is filled with an alcohol or oil solution, the freezing point of which is significantly lower than that of ordinary water. Therefore, it became possible to work with a bubble building level at subzero temperatures. Solutions are tinted for brightness of perception. They are distinguished by less fluidity than water, due to which the air bubble in the flask moves with agility sufficient for a calm visual fixation of its position.

Convenience and extras from manufacturers

The building-grade body comes in a regular rectangular or T-section. The shape of the body does not affect the result of the readings at all, but it can be convenient or inconvenient for a particular human hand. Determining the ergonomics of a device is a purely personal matter, but it is advisable to test it before purchasing it. To test for convenience, you simply need to hold the instrument in your hands and compare several options.

Among the options offered by manufacturers to facilitate work with the building level:

• A magnifying lens that allows you to read instrument readings without strain;
• Introduction of fluorescent components into the liquid to make it possible to read readings in low light conditions;
• Rubberized grip-type openings for improved ease of use;
• Magnetic inserts on the edge applied to the surface being tested for fixation on metal structures;
• Rulers that allow you to simultaneously control geometric parameters while checking verticals and horizontals.

Models of building levels are produced with or without the listed additions. Nevertheless, the main convenience is rightfully recognized as the size of the ampoules, the pleasant brightness of the liquid and the clarity of the scale.

Those wishing to buy a level with useful options should consider using them. They will certainly increase the price of the instrument. Is it reasonable to overpay for something that is absolutely not necessary to solve already set or just planned tasks?

Consideration of application prospects

Rack and pinion control devices are now also available in electronic form, but the demand for conventional bubble ones has not fallen at all. Simplicity is captivating. After all, it has been proven by practice that the simpler the device, the more reliable and longer it serves the owner.

A simple device is easier to learn, maintenance is not difficult, and it almost never requires expensive repairs.

To perform various control operations, levels are produced in lengths from 0.4 m to 2.5 m. Depending on the brand, the spread may be in both directions from the specified limits. When thinking about the question of which construction level of the bubble group is best to choose for domestic needs, you need to focus on your own needs and real prospects.

Please note that devices:

• Lengths from 2 m or more are intended for checking the planes of floors and walls, for checking the quality of screeds, and leveling with plaster;
• Lengths ranging from 1 to 2 m are used to check evenness brickwork, geometric data of suspended and suspended ceilings;
• Lengths ranging from 0.4 to 1 m are suitable for arranging window and doorways, for installing and hanging a variety of household appliances, for performing various finishing and repair operations.

Do not forget that the storage location for building levels over 2 m in length must be taken care of in advance. We remember that the error of long devices is much less than that of their short counterparts.

Noteworthy Aspects

It was not for nothing that the simplicity of the design inspired the counterfeit sculptors with vague thoughts about the possibility of serial production of counterfeits. Checking the documents for products before purchasing will save you from offensive mistakes and from buying “left” devices.

Products domestic producers must comply with the GOST 9416-83 protocol, devices from foreign manufacturers must comply with ISO 9001 regulations.

In addition to checking technical documents The buyer of the bubble building level needs:

• Thoroughly examine the condition of the main elements of the device - ampoules with liquid;
• Decide on the size of the devices and the color of the liquid;
• Inspect the fastenings. There are models on sale whose flasks are secured with adjusting screws. Whether they are needed or not is a controversial issue. According to experts, levels should not be adjusted independently. The result of the efforts of ignorant people is too dubious.
• Examine the clarity of the metric scale and protractor divisions, if there is an ampoule for monitoring angular directions;
• Test ergonomics, i.e. hold in hands;
• Examine the condition of the body.
• Check the accuracy of the readings.

Most specialized stores have stands with a perfectly horizontal surface.

Let's say you buy a level in a newly opened point of sale or in the online store. In such situations, the accuracy of the readings of the control device is checked as follows:

• Let's find a horizontal platform on which the tested level can freely fit. Without instrumental definitions, it should appear almost flat;
• We apply the tool to the surface. Using a marker or pencil, we outline the outline of the corners so that the level can be put back in the same place.
• We fix and remember the position of the bubble. We note how much he deviated from the risk.
• We turn the level 180º and set it according to the marks made earlier.
• We fix the position of the bubble. If he took a similar position, there was no doubt about the accuracy of the device. If not, check a couple more devices.

The ampoule responsible for the verticals is checked using an identical method, but on a vertical plane. There is also a popular method of applying two spirit levels to each other with their working edges. According to this method, the position of the bubbles must be the same, otherwise one of the devices is blatantly lying.

There are also tips according to which to check rack and pinion device the horizontal line is marked with a water level or a laser level, the principle of operation of which should also be studied.

The simplest water level

The device consists of two equal-volume flasks connected to each other by a flexible thin hose. Used in marking horizontal lines if the layout needs to be done in different rooms or over long distances. Those. where the use of a laser level is impossible, unprofitable or pointless.

The principle of operation of an elementary device is based on the law of communicating vessels. The water level in both communicating vessels will always be at the same absolute level, for fixing which on the flasks there are risks.

The use of a water device allows you to correctly mark horizontal lines regardless of the actual position of the surfaces of the floor, ceiling, parapet, etc. No digital device has yet been able to replace it. Note that the water level sets off a reference horizon, from which the heights designated by the project are then laid off. It is not used to directly mark future planes formed by a suspended ceiling, joists or installation points for plumbing fixtures, etc.

To mark the water level, we will invite an assistant, we will proceed as follows:

• We mark an arbitrary point on the wall at a distance from the floor convenient for marking;
• We apply one of the flasks to the point, fix and remember at what point the water level is established;
• We send an assistant to the desired point. By moving his flask up/down along the wall, he must find a position in which the water level will be at the same level.

Strong advantages of the device: low cost, simplest operation and accuracy. Disadvantages: inability to carry out breakdown at subzero temperatures, limited use, need to wait until the level is established in both flasks.

Advanced laser devices

Buying a laser level for use at home is considered unprofitable. Why do you need an expensive device if the markings can be done using a water level and a ruler? However, for owners who have decided to seriously equip their country estates, a laser device will certainly come in handy. It will help to break down open areas and indoor spaces, ensure the accuracy of vertical and horizontal lines, and, if necessary, mark entire planes in the space being processed.

Various models of laser devices are used in construction: from compact pocket devices with a built-in laser pointer to highly complex multi-prism devices that allow marking in three mutually perpendicular planes.

The miniature version is ideal for everyday household needs and cosmetic repairs. To carry out in-depth redevelopment, fundamental leveling of surfaces, and laying pipelines, it is advisable to acquire a serious laser level installed in a stationary position on a tripod or on a wall bracket.

Most lasers used in construction target only verticals and horizontals. Some new modifications are equipped with a function for breaking out inclined lines, required when constructing stairs, for example. Instructions for use are simple; manufacturers include a detailed description of the device. The optimal color of the laser beam is green, because... it does not irritate the eyes, and is also perfectly readable in a brightly lit room and in an open area in sunny weather.

Videos with a detailed explanation of how to correctly choose the right device will help to finally clarify the issue.

Overview of bubble type devices:

Checking the accuracy of the bubble level:

Analysis of compact laser levels:

Let's summarize. A rack-type building level with bubble “sensors” is not used for marking. With its help, the horizon and verticals of constructed and restored structures are checked. The breakdown of the premises and construction site is carried out using laser devices. If the laser is not affordable, marking is done with the good old plumb line paired with a water level. There is no universal device; each of them performs its own functions.

When wondering how to choose a building level, any person is aware of the consequences of a wrong decision.

A common type of bubble level is its rectangular modification, which is inexpensive.

After all, any, even the slightest deviation from a flat surface can lead to the most disastrous consequences, including a complete redo of the just completed repair. Therefore, the question of how to choose a building level should be treated with the utmost care, because this tool comes in several different types, the properties, purpose and price of which may vary significantly.

Currently, the market has a fairly wide range of these construction tools. One of the most common measuring instruments This type is the bubble level. It consists of a body and a flask filled with liquid in which an air bubble floats. This level is very simple and at the same time quite accurate and reliable.

What are the types of levels

The principle of operation of a water level.

Bubble levels. The most common type of this level is its rectangular modification. Its length varies widely and can be 2.5 meters. The minimum size is 20 cm. However, occasionally you can find devices of a telescopic design, the length of which reaches 4 meters. Their flasks are made of impact-resistant transparent material. Alcohol is used as a filler.

Some of these tools are equipped with magnets, which makes them much easier to use on steel surfaces. There is also a type of level that is used when working with pipes: such tools are usually small in size and have a semicircular recess running along the body. Thanks to it, the device is well held on the surface of the pipe. These tools have a low price, but versatility is not their thing. strong trait, so it is better to choose a different type of level.

Water levels. This type of measuring instrument, otherwise known as a hydraulic level, is well suited for measuring the deflection of large horizontal surfaces. It consists of two containers filled with liquid, which are connected to each other by a hose. The main feature of these levels is that their length ranges from 5 to 25 meters, which makes them indispensable when working with extended surfaces and at the same time absolutely useless for use in an apartment.

Operating principle of a laser level.

They are sensitive to high temperatures, so they should be stored away from heat sources. You also need to ensure that when filling containers with water, no air bubbles get into it, as this significantly affects the readings of this measuring device.

Laser levels. Measuring instruments of this type are among the most accurate and at the same time the most expensive. Their main advantages are their small size and large range, which can reach several tens of meters. They are also best suited for measuring large and extended surfaces, since the laser beam emitted by this instrument can be turned into a plane. In addition, they perform well when laying out directions. For ease of use, such measuring instruments are equipped with tripods and magnetic suction cups.

Top tools have not one laser beam, but several. They can intersect with each other, facilitating and clarifying measurements.

This device can definitely be called the best among all levels. It is versatile, accurate, compact and practical. It has only one drawback: its high price.

Choosing a level in the store: what to look for

The type of measuring device largely depends on how large-scale problems will be solved with its help. After all, it’s one thing when a level is selected for frequent use on large scale construction work oh, and it’s completely different when it’s needed only to level the floor in the apartment.

There is no need to be influenced by the products of famous brands and choose the most famous brand, because the main thing in any thing is its quality, and this indicator often has nothing to do with a big name.

How to choose a bubble level

Bubble level diagram.

First of all, you need to decide for what tasks you need this measuring tool. If you are going to level the walls with it, then you need to choose a level maximum length, if the question is posed much more modestly and you just need to attach bookshelf, then the tool, accordingly, should also be smaller.

The air bubble itself should be clearly visible, and the marks on the level flask should be black and there should be several of them. These marks should be very close to each other, forming something like a scale.

After this verification step, you can proceed to the next one and test the accuracy of the device. If the purchase is made in a specialized store, then it probably has special stands that are specifically designed for testing such measuring instruments.

For the test, the device should be positioned horizontally and the location of the air bubble on the flask scale should be accurately remembered, then the level should be rotated 180 degrees. If everything is in order with the device, then the bubble will not change its position relative to the scale.

After this, you need to check its operation in the vertical plane. To do this, select the appropriate stand to which the device is applied. Then everything happens as in the previous case: the location of the bubble is remembered, then a rotation of 180 degrees follows. If the bubble remains in its place in this case, it means that the level is made with high quality and you can safely buy it.

If there is no such stand in the store, when you arrive home, you need to invite a person who has a level or laser level and, using these tools, check the correct operation of what you purchased. If you are not satisfied with something, then you always have the opportunity to return the purchased device back to the store.

What to look for when buying a laser level?

If you have made a choice in favor of a laser measuring device, then when purchasing, you should first of all pay attention to its technical characteristics, the main of which are measurement error and range. The accuracy of the laser level must be at least 3 mm for every 10 meters, and the range must be at least 20 meters.

Often this device comes with special glasses that allow you to better see the laser beam.

In addition, these devices are equipped with two types of lasers, which differ in the color of the beam they emit. The most common emitters are those that produce a red color, but if possible, it is better to choose an instrument with a green beam, since this color is more noticeable and contrasting to the human eye. However, levels with a green laser are somewhat more expensive than their “red” counterparts.

It is worth looking carefully at what is included with the device.

It is often very diverse and includes both many useful items and those that you can completely do without.

If, along with the purchase of a laser level, you are going to purchase some kind of addition to it, then be sure to consult about this with sellers or with friends who understand such things, so that it does not happen that the purchased accessory does not suit your type of device.

Purchasing a level is a very important step, on which the quality of the upcoming repair directly depends.

How to choose a building level? And which one is better?

The final result of the work of a number of specialists depends on the accuracy of measuring instruments. industrial areas: builder, mason, carpenter, etc. The construction level of various modifications is a simple but mandatory tool for any serious team or individual craftsman, which allows you to determine the accuracy of the location of horizontal and vertical surfaces. The history of the appearance of the first spirit level dates back to the second half of the 17th century, and the vertical plumb line is a well-known primitive prototype of later inventions.

Generally accepted classification for building levels:

• Bubble (spirit level) - with flasks filled with liquid installed in a rigid body, and the presence of a floating air bubble in each flask;
• Laser level – with fast and clear marking of working surfaces with a laser beam point;
• Water level (hydraulic level) – the operating principle is based on Pascal’s hydrostatic law and checks the conformity of the planes of horizontal surfaces.

Despite all the obvious innovative advantages of the same laser level, skilled craftsmen never refuse to use a high-quality bubble level - this universal tool, time-tested.

Basic characteristics of the building level

• Measurement accuracy (from 0.3 mm/m, the longer the building level and the heavier it is, the higher the accuracy of its readings);
• Impact resistance. As a rule, levels have a hollow body, but with walls of sufficient thickness;
• Wide resistance to the slightest bending and torsion;
• Measuring flasks with a high degree of transparency and resistance to discoloration, clouding, cracking and leakage when exposed to low and high temperatures, as well as ultraviolet rays.

Device

A rigid monolithic, most often rectangular body with a milled bottom edge is made of light and durable materials (aluminum, polystyrene, plastic, wood) with an anti-corrosion coating. In the case, depending on the required accuracy, a certain number of transparent sealed glass flasks(level eye) with an air bubble floating in a colored alcohol-containing liquid:

• one bulb - only for the horizontal guide (180 degrees);
• two - for horizontal (180 degrees) and vertical guides (90 degrees);
• three - for more complex work, with an additional third camera that controls the measurement of the angle of inclination (rigidly fixed at 45 degrees, or rotating - to measure any angle of the controlled surface).

In order to minimize errors in angular vision, limiting lines - risks - are applied to the surface of the measuring flasks. Eyes for checking the position of surfaces of the vertical plane and the angle of inclination have built-in mirror reflectors for simultaneous monitoring of the position of bubbles.

Plastic plugs at the ends of the level protect the structure in case of accidental falls.

Some level manufacturers also provide additional amenities: for example, a built-in magnifying lens for more comfortable to the eye bubble control, magnetic systems or fluorescent liquid flasks to allow work to continue even in the dark.

The principle of operation of the building bubble level is simple: measuring and adjusting surfaces relative to horizontal and vertical planes occurs due to the movement of the bubble inside a certain level eye. The result of a correct setting will be that the bubble is located exactly in the middle between the measuring marks of the flask.

Building level. Which is better?

Having decided to purchase a building level, it would be a good idea to familiarize yourself with some recommendations for choosing it:

1. The flask must be securely attached to the body. When purchasing, you should avoid the level in which the bulb is screwed on with screws, which is why it may become loose over time. You should choose flasks made of polyacrylic, which is stronger than glass and more transparent than plastic.
2. Length of the level - it is necessary to take into account the type of work to be done, since the larger the working area, the longer the level should be chosen;
3. Defects - the building level is a measuring device, so when buying a tool you must make sure that there are no manufacturing defects, as well as errors in the readings.

1. Body material - the instrument can be made of plastic, metal or wood. The most reliable and durable is, of course, a metal level, inside of which there are stiffening ribs
2. Marking - the best option is to place control strips inside the bubble itself. The divisions applied to the surface of the flask should be clear and located close to each other.

The range in cost of building levels is quite varied. At the same time, it is not worth choosing more economic models, especially if you need to use the tool repeatedly. If you have to carry out a major repair, experts strongly recommend purchasing a professional tool. Its characteristic feature is the presence of a shock-resistant case with special rubber pads, which during operation can soften impacts from falls, etc.

In operation, the construction level of the famous German brand “Stabila” has proven itself better than others. On average, you will have to pay from 700 to 1800 rubles for such a tool. This measuring device is famous for such advantages as:

• high-quality and stable reading (high degree of measurement accuracy);
• good ergonomic characteristics;
• precision in the geometry of the aluminum profile body.

In addition, this brand also produces magnetic building levels, which make it possible to work with electricity and are equipped with special slots for marking for switches and sockets.

In addition to Stabila, another good option may become a construction level of the Akula company. The good thing about the levels of this brand is that they are not afraid of falls and shocks. Also, good models are produced by Ermak, Bosch or Kapro. For example, the Kapro company constantly updates its models and often introduces the latest innovative solutions, producing household and professional-type tools. High quality models differ German company"Bosch". A similar tool to the Bosch models is also produced by the Russian company Condtrol, which is more affordable in terms of cost.

In the middle category of such instruments, it is worth highlighting the levels produced by the companies “Matrix”, “Brigadier” and “Stayer”, which are distinguished by their particular measurement accuracy and optimal cost-to-quality ratio.

However, when purchasing a builder grade, a well-known brand should not be the deciding factor. The main thing is to decide on the type of future work and the frequency of use of the tool.

180 degree method

You can check the accuracy of the level in the simplest way, called the 180 degree method:

1. It is necessary to place the building level tightly, without gaps, on a flat horizontal surface and remember the position of the bubble relative to the marks.
2. In the horizontal plane, turn the level 180 degrees and place it clearly on the same area.
3. At a qualitative and accurate level, the position of the bubble should remain the same.

In the same way, you can check the accuracy of the vertical readings.

Round bubble level

This type of building level is designed to control only horizontal surfaces and is somewhat different from the usual levels in the design of the body, but the principle of operation remains unchanged. The round level is a sealed hemispherical capsule made of impact-resistant glass, with a fixed flask, inside which the position of the bubble is determined by a bounding round line.

The scope of application of the round bubble level is not only construction work and monitoring the degree of shrinkage of already rebuilt buildings. These kinds of levels are widely used in photo and video shooting to strictly adjust the horizontal position of the equipment tripod. It is very common to use round levels when installing commercial or control scales, as well as for constant monitoring of the stable horizontal position of stationary machines, industrial tools and even jewelry surfaces - for example, polishing wheels.

A round bubble level often has the ability to be locally attached to the surface being tested and is very low in cost with high measurement accuracy. Knowledgeable person will appreciate this simple and necessary tool.

Ubiquitous use of levels

Whatever work you have to do (check the vertical and horizontal consistency of the surface of the walls, floor and ceiling; install a washing machine without distortions, hang a bookshelf or a picture) - the simplicity and ease of using a bubble building level will help you do it quickly and with the highest quality. Even if there is a laser level or plane builder that is more complex in design and principle of operation, the construction level, which is unchanged in the arsenal of any master, will not remain idle.

A building level is a device designed to control the installation of devices, materials, structures in vertical and horizontal planes, as well as to check the clarity and correctness of the lines.

Modern construction technologies require the use of only high-quality materials and high-precision tools. Quite often, the overall result of repair or construction depends on strict adherence to the clarity of lines.

One of the main tools that allows you to keep all planes perfectly level is the building level. Control of vertical and horizontal lines is carried out using different types of building levels: rack, hydraulic or laser.

Helpful information:

In order to determine which building level is best suited for your needs, first consider their design and features of use.

Bubble (rack) levels

The rack level is a rod with three cones at different ends. Each of them contains an air bubble placed in a tinted liquid. The cones also contain special marks, according to which the necessary measurements are made.

Bubble levels are so called because of the presence of cones filled with liquid (non-freezing in the cold) with an air bubble left behind. There are marks on the cones that help determine the position of the bubble relative to the earth's surface, and depending on the position of the cone, it indicates the horizontal or vertical of the object being measured.

The basis for the operation of this level is the movement of the bubble in the cone relative to the horizon level. The cone located in the middle is responsible for controlling horizontal lines. The other, located at one end of the staff, helps when measuring vertical lines. The third cone is installed at an angle and allows you to maintain the plane at a 45-degree angle.

When choosing a building level, you should also pay attention to its design, or rather the design of the slats. It can be of two types: rectangular and I-beam (in the form of a rail).

Rectangular levels are popular among amateur models that are used in everyday life. I-beams, on the other hand, have earned attention from professional builders due to their “survivability”. Such levels do not deform when dropped from a height or during prolonged intensive use.

The cross-sectional shape is not the only structural feature of the building level that you should pay attention to. Levels of different lengths are designed for different types of construction work. With their help, the evenness of lines and planes is monitored in a wide variety of conditions.

Slat levels exist with varying amounts ocelli (cones), for example:

• Single-eyed (horizontal)
• Two-eyed (horizontal and vertical)
• Three-eye (the most common type of slatted level), in such levels two eyes are fixed motionless (horizontal and vertical) and one eye is adjustable (with a degree scale to determine the angle of inclined surfaces)
• Five-eye levels are special plumbing levels for laying water and sewer pipes at a certain angle.

There are bubble (rack) levels various sizes– from 20 cm to 2.5 meters.

To check the bubble level, place it on a flat surface, mark the position of the bubble relative to the marks, and then turn it the other way. If the bubble has not changed its position relative to the marks on the flask, then the level is accurate. Thus, it is necessary to check the readings of each cone.

Hydro levels (water levels)

The hydraulic level is another type of building level. It is a transparent tube, at the ends of which there are flasks with marks. Its functioning is ensured by the laws of physics and the principle of communicating vessels.

The liquid level in the flasks remains the same and constant, regardless of the height of one of them. In order to use the hydraulic level, you need to fill it with water. Try to avoid getting any bubbles into the tube, as... Each bubble will significantly reduce the accuracy of the construction tool.

To carry out correct measurements of the hydraulic level, you will need an assistant; you will not be able to do it yourself. Everyone takes a flask in their hand and opens the lids on them to prevent water from leaking out. One flask is pressed against the wall near the mark, and the other in the place where the mark needs to be applied. After this, the first flask is lowered or raised until the water level in the flask and the mark on the wall are in line.

The water level in the second flask will indicate a point that is located in the same horizon as the mark. It is imperative to wait until the water in the flasks and tube calms down, otherwise it will not be possible to carry out correct calculations.

After it has been possible to obtain two marks in the same horizon, they are connected to each other by pulling a string or drawing a line. Such levels are used at fairly large distances. The sizes of hydraulic levels range from 3 to 25 meters

Using a hydraulic level you can only mark horizontal lines, for vertical lines it is necessary to use a different type of building level.

By doing finishing works in rooms with small square footage it is not recommended to use a hydraulic level. Its minimum length is five meters, which makes it difficult to work with in small spaces.

When choosing a hydraulic level, you should pay attention to the shape of the flasks. Preference should be given to rectangular rather than cylindrical ones. It is easier to work with this level, because It is more convenient to press the flasks against the wall and make marks. The diameter of the tube also plays a role; the larger it is, the faster water in flasks is installed at the same level. The diameter of the tubes varies from 6mm to 8mm.

Laser level

The third type of building level is a laser level. This type of construction equipment is more modern and accurate compared to those described above. Equipped with various electronic technological solutions, it allows measurements in various planes with maximum accuracy.

Today, it is the most convenient and accurate control and measuring device that allows you to accurately and efficiently construct lines in various planes. Laser levels can be mounted on tripods, magnets, sliding rods or special brackets. The most common models of laser levels are the so-called “self-leveling levels”, in which the beam-projecting part works on the principle of a pendulum, that is, it levels itself relative to the surface of the earth independently.

There are several types of construction laser levels:

1. A classic slatted level with a built-in laser pointer, with which you can project a laser beam onto a plane.
2. The so-called laser level, which can be independently installed in a level.
3. And the last, most technically advanced one is the plane builder. It has the ability to project several laser beams at once onto a wide variety of planes.

Technical perfection and versatility make the laser construction level the most preferable for purchase, but it also has the highest price.

Selecting the optimal level length. Here you need to determine for what work you plan to use it. If it's facing tiles, then you will have to purchase two levels: short (up to 60 cm), to control the level between adjacent tiles; long (200 cm), to control the level of the entire cladding plane.

When installing plasterboard structures, pouring screed, plastering walls, it is necessary to purchase a long, at least 200 cm, building level. Thus, the larger the working area, the longer the level you need to buy.

The presence of all kinds of additional design features. Built-in magnets allow you to attach the building level to metal structures, freeing your hands. The slots on the rail make it easier and more secure to hold the level in your hand. Rubberized linings protect against slipping and act as shock absorbers if the level drops.

The building level is a control and measuring device, therefore, when purchasing it, it is necessary to check for the absence of manufacturing defects and errors in the readings. To check the correct determination of the horizontal position, you can use a horizontal stand (available in large hardware stores).

If there is no stand in the store, you can put the level on any horizontal surface and, turning it 180 degrees, check the position of the bubble. If it has not changed, then the level is correct. The correctness of the readings of the vertical flask is checked by applying the level to a wall or other vertical surface. The constant position of the bubble indicates the serviceability of the flask.

Levels in which the flasks are securely fixed are more reliable and accurate. You should not buy models with screwed flasks; it is better to choose ones with tightly mounted ones. It is worth paying attention to this, because over time the screws become loose and they constantly need to be tightened and the accuracy of the level checked.

In addition to the above-mentioned design features of fastening the flasks, you should also pay attention to the quality of the fastening. If the flasks are not installed securely enough, then over time they will become loose and the level will become unusable.

When considering the prices of different types of levels, you should not opt ​​for the cheapest options. Such building levels are short-lived, require constant adjustment, and may give incorrect readings. You shouldn’t skimp on instrumentation, because the result of construction and repair work will depend on them.

If you decide to buy a laser level, then saving here is even more inappropriate. Such things cannot be cheap, unless they are fake or defective. But here it is important to understand that if you need the level for one-time work (for example, installing interior doors), then it doesn’t make much sense to spend money

Always keep your receipt! It may happen that you only determine the defect or inaccuracy of the purchased level at home after some time. Most often this happens when you double-check planes at different levels. Professional builders use a whole range of measuring instruments. Each of them is adapted for a specific type of work and conditions, and therefore cannot be called interchangeable. They complement each other perfectly and “back up”. Therefore, in order to be able to replace or return a low-quality level, save the receipt.

We hope our advice will help you decide which building level to choose for your specific needs.
