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 of this type is 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 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 strong point, 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. 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 the level of maximum length, but if the question is posed much more modestly and you just need to attach a 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 manufacturers of levels also provide additional amenities: for example, a built-in magnifying lens for more comfortable control of the bubble, magnetic systems or fluorescent liquid flasks for the ability to continue work 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 it performs better than others, the construction level of the famous German brand"Stabila". 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 could be the 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. Models from the German company Bosch are distinguished by their high quality. 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. A knowledgeable person will appreciate this simple and necessary tool.

Ubiquitous use of levels

Whatever work has to be done (check the compliance of the vertical and horizontal surfaces of the walls, floor and ceiling; install without distortions washing machine, hang a bookshelf or a picture) - the simplicity and ease of using a bubble building level will help you do this 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.

With the advent of computer and Internet technologies, all stages of obtaining information have become much easier and faster. In order to introduce this progressive tool into all industries, almost every modern organization requires its employees to have PC knowledge to one degree or another. When applying for a job, the applicant must indicate his level of computer use in the application form. If a person does not have such experience, then it is much more difficult for him to find a suitable vacancy.

In most cases, a person determines his level of PC use independently. Currently, there are no standardized programs for this purpose that are common to all.

PC usage levels

There are several levels of using a personal computer.

The lowest level user is called a "teapot". A person who has only general knowledge, as a rule, uses a computer only to communicate on social networks and on dating sites. Such a user does not know the basic meanings of keyboard shortcuts and the purpose of programs.

The second level includes an ordinary user. He, in turn, knows the necessary basics, knows how to work in Microsoft programs Office knows how to connect a keyboard and mouse. But his knowledge is not enough to use auxiliary keyboard shortcuts; all operations and manipulations are carried out exclusively using the mouse.

The third level is a confident PC user. He knows minimum required main installed programs, architecture personal computer, can explain what is inside the system unit and what is used for what. Confident user can independently reinstall the operating system and drivers, and easily uses search engines.

An advanced user knows everything about the hardware and software of a computer. He is able to disassemble and assemble a PC from components himself. Uses function keys with ease. Can independently correct some computer malfunctions.

The next level includes programmers and graduates of technical universities. A person of this level of knowledge will be able to assemble not only a computer, but also an entire server, can also set up a network, and is quite well versed in writing programs in various languages.

A hacker has the most advanced level of PC knowledge. This word speaks for itself. The hacker knows absolutely everything. Can bypass numerous passwords and hack some servers.

When building a house, major or cosmetic repairs, assembling and installing furniture, one of the necessary tools is a construction level. It is this that allows you to clearly determine the deviation from the vertical or horizontal line. The construction products market is annually replenished with many models that differ in technical characteristics and operating principles. Having studied the rating of the best samples, everyone will be able to accurately determine the most suitable option for themselves.

Surely many have heard about the international system of English language levels, but not everyone knows what it means and how to classify it. The need to find out your level of English proficiency may arise in some life situations. For example, if you need to pass an interview at work or at the embassy, ​​if you need to pass some kind of international exam (IELTS, TOEFL, FCE, CPE, BEC, etc.), when entering a foreign educational institution, when getting a job in another country, and also for personal purposes.

International system Definitions of knowledge of the English language can be divided into 7 levels:

1. Beginner – Initial (zero). At this level, the student knows practically nothing in English and begins to study the subject from scratch, including the alphabet, basic reading rules, standard greeting phrases and other tasks of this stage. At the Beginner level, students can usually answer questions easily when meeting new people. For example: What is your name? How old are you? Do you have brothers and sisters? Where are you from and where do you live? etc. They can also count to one hundred and spell out their name and personal information. The latter in English is called spelling (pronouncing words by letter).

2. Elementary. This level immediately follows zero and implies knowledge of some basics of the English language. The Elementary level gives students the opportunity to use previously learned phrases in a more free form, and also instills a whole range of new knowledge. At this stage, students learn to briefly talk about themselves, their favorite colors, dishes and seasons, weather and time, daily routine, countries and customs, etc. In terms of grammar, at this level there is an initial introduction to the following tenses: Present Simple, Present Continuous, Past Simple, Future Simple (will, to be going to) and Present Perfect. Some modal verbs (can, must) are also considered. different types pronouns, adjectives and degrees of comparison, categories of nouns, forms of simple questions. Having firmly mastered the Elementary level, you can already take part in the KET (Key English test).

3. Pre-Intermediate – Below average. The level following Elementary is called Pre-Intermediate, literally translated as Pre-Intermediate. Having reached this level, students already have an idea of ​​how many sentences and phrases are constructed and can speak briefly on many topics. The Pre-Intermediate level adds confidence and expands learning potential. Longer texts appear, more practical exercises, new grammatical topics and more complex sentence structures. Topics encountered at this level may include complex issues, Time Past Continuous, different forms of the future tense, conditional sentences, modal verbs, infinitives and gerunds, repetition and consolidation of Past Simple (regular and irregular verbs) and Present Perfect, and some others. In terms of oral skills, having completed the Pre-Intermediate level, you can safely go on a journey and look for every opportunity to use your knowledge in practice. Also firm ownership English language at the Pre-Intermediate level, it gives you the opportunity to take part in the PET (Preliminary English Test) test and the BEC (Business English Certificate) Preliminary exam.

4. Intermediate - Average. At the Intermediate level, the knowledge acquired at the previous stage is consolidated, and a lot of new vocabulary, including complex ones, is added. For example, personal characteristics of people, scientific terms, professional vocabulary and even slang. The object of study becomes active and passive voices, direct and indirect speech, participial and participial phrases, phrasal verbs and prepositions, word order in complex sentences, types of articles, etc. From grammatical tenses, the difference between Present Simple and Present Continuous, Past Simple and Present Perfect, Past Simple and Past Continuous, as well as between various forms of expressing the future tense is examined in more detail. Texts at the Intermediate level become longer and more meaningful, and communication becomes easier and freer. The advantage of this stage is that in many modern companies employees with knowledge of the Intermediate level are highly valued. This level is also ideal for avid travelers, as it makes it possible to freely understand the interlocutor and express himself in response. From international exams, after successful completion intermediate level, you can take the following exams and tests: FCE (First Certificate in English) grade B/C, PET Level 3, BULATS (Business Language Testing Service), BEC Vantage, TOEIC (Test of English for International Communication), IELTS ( International English Language Testing System) for 4.5-5.5 points and TOEFL (Test of English as a Foreign Language) for 80-85 points.

5. Upper Intermediate - Above average. If students reach this level, it means that they can freely understand fluent English speech and communicate without difficulty using that language. lexicon which you have already purchased. At the Upper-Intermediate level, it becomes possible to use English much more in practice, since there is a little less theory, and if there is, it basically repeats and consolidates the Intermediate level. Among the innovations, we can note Narrative Tenses, which includes such difficult tenses as Past Continuous, Past Perfect and Past Perfect Continuous. Also covered are the Future Continuous and Future Perfect, the use of articles, modal verbs of assumption, verbs of indirect speech, hypothetical sentences, abstract nouns, causative voice and much more. The Upper-Intermediate level is one of the most in demand both in business and in the educational sphere. People who are fluent in English at this level can easily pass any interviews and even enter foreign universities. At the end of the Upper-Intermediate course, you can take exams such as FCE A/B, BEC (Business English Certificate) Vantage or Higher, TOEFL 100 points and IELTS 5.5-6.5 points.

6. Advanced 1 – Advanced. Advanced 1 level is required for professionals and students who want to achieve high fluency in English. Unlike the Upper-Intermediate level, many interesting phrases appear here, including idioms. Knowledge of tenses and other grammatical aspects previously studied only deepens and is viewed from other unexpected angles. Topics of discussion become more specific and professional, for example: environment and natural disasters, legal processes, genres of literature, computer terms, etc. After the Advanced level you can take a special academic CAE exam(Cambridge Advanced English), as well as IELTS 7 and TOEFL 110 points, and you can apply for a prestigious job in foreign companies or a place in Western universities.

7. Advanced 2 – Super advanced (native speaker level). The name speaks for itself. We can say that there is nothing higher than Advanced 2, because this is the level of a native speaker, i.e. a person born and raised in an English-speaking environment. With this level you can pass any interviews, including highly specialized ones, and pass any exams. In particular, the highest test of English proficiency is the academic exam CPE (Cambridge Proficiency Exam), and as for the IELTS test, with this level you can pass it with the highest score of 8.5-9.
This gradation is called the ESL (English as a Second Language) or EFL (English as a Foreign Language) level classification and is used by the ALTE (Association of Language Testers in Europe) association. The level system may vary depending on the country, school or organization. For example, some organizations reduce the 7 levels presented to 5 and call them a little differently: Beginner (Elementary), Lower Intermediate, Upper Intermediate, Lower Advanced, Upper Advanced. However, this does not change the meaning and content of the levels.

Another similar system of international examinations under the acronym CEFR (Common European Framework of Reference for Languages) divides the levels into 6 and has other names:

1. A1 (Breakthrough)=Beginner
2. A2 (Waystage)=Pre-Intermediate – Below average
3. B1 (Threshold)=Intermediate – Average
4. B2 (Vantage)=Upper-Intermediate – Above average
5. C1 (Proficiency)=Advanced 1 – Advanced
6. C2 (Mastery)=Advanced 2 – Super advanced
