The Indiv 5 counter and its improved modification Indiv 5r are radiator distributors, allowing you to organize heat metering for each individual apartment. These devices are intended for buildings with vertical wiring heating, that is, for almost all modern multi-storey buildings.

Operating principle

The Indiv 5 heat meter measures and records the temperature difference between the radiator and the air in the room. The temperature sensor is built into the Danfoss Indiv 5 housing. The air temperature is programmed as a constant value of 20° C. Such averaging introduces a certain error in the Danfoss Indiv 5 readings, however, this is not such a serious problem. But the rest of the calculations will be carried out with maximum accuracy, even if the Indiv 5 meter distributor is covered with thermal insulation.

The data is displayed on the LCD screen. Even a person who is far from technology will not have any problems with how to take readings on Indiv 5. The monitor alternately displays:

• up-to-date information;
• data based on the results of the previous time period;
• end date of the current Danfoss Indiv 5r work cycle;
• calibration factor;
• checksum, etc.

All calculations are performed automatically software AMR provided management company, on whose balance sheet the house is located.

Installing a Danfoss heat meter on a radiator is not very difficult. The device is mounted on a surface heating equipment using the installation kit. It is important to strictly adhere to the Indiv 5 manufacturer's instructions regarding installation rules for specific devices. Sometimes a situation arises when it is not possible to attach the radiator meter distributor Indiv 5 to the surface of the battery. In such cases, you will have to install a remote sensor with connecting cable and disable the built-in one. This solution is usually intended for units with a casing.

The price of the Indiv 5 distributor installed on the meter will not hit your budget too much. However, it is worth purchasing a device only when the housing company has organized the appropriate recalculation based on the readings of individual and general house metering devices. To do this, it is necessary that such regulators and distributors be installed in at least half of the apartments. If you are interested in where to buy Indiv 5r in Moscow and other helpful information for equipment, we are waiting for you on our website.

You can order radiator heat meters (distributors) from the TEPLOSTOK company. We are pleased to offer products famous brand INDIV, as well as all the necessary components for it on favorable terms.

Relevance of using the presented models

Individual heat metering allows you to save thermal energy and pay for it according to actual consumption. In systems with vertical wiring, radiator counter-distributors are used.

The models presented in our assortment meet all established requirements and have a calibration interval of 10 years.

Main models of heat spreaders

1. Versions INDIV-3 and INDIV-3R. These distributors have one built-in temperature sensor. Such devices use the principle of accumulating the resulting reading over time at a rate that is determined by the output signal of the built-in sensor.
2. Versions INDIV-3R2 and INDIV-3RD. These models have 2 temperature sensors (surface heating device and ambient air). In the INDIV-3R2 distributor both sensors are built into the housing. In the NDIV-3RD device, the air temperature sensor is built-in, and the surface sensor of the heating device is remote.

All types of distributors allow you to store and display the resulting reading on a preset day of the year. The devices are used in internal systems heating.

Any distributor can be installed on:

1. Sectional radiator made of cast steel or cast iron.
2. Aluminum battery heating.
3. Tubular and panel radiators.
4. Pipe registers.
5. Convectors.

The heat distributor solves the following problems:

1. Accumulation of consumption readings.
2. Indication of consumption readings for the previous year.
3. Checksum indication for verification.

In addition, the distributor is equipped with a self-testing system.

Technical characteristics of INDIV-3:

1. Range of design temperatures in heat supply systems: 55-105 degrees Celsius.
2. Starting reference temperature: June-August: 40 degrees Celsius, September-May: 30 degrees Celsius.
3. Power supply for heat distributors: lithium battery.

Electronic devices for distribution of thermal energy INDIV-5, INDIV-5R, INDIV-5R-1 are designed for measuring the temperature of a heat-receiving metal plate fixed on the surface of a heating device and presenting the measurement result on an accrual basis in the form of a time integral (formula /1/), proportional to the thermal energy supplied by the heating device.

Description

The operating principle of electronic devices for distributing thermal energy INDIV-5, INDIV-5R, INDIV-5R-1 is based on measuring the temperature tm of a heat-receiving metal plate fixed to the surface of the heating device. The measured temperature is used to calculate the temperature difference At =(tm - 20) °C and calculate the time integral. The device displays the resulting dimensionless integral value, on the basis of which the relative share of heat transfer from a given heating device in a collective heating system can be calculated. Electronic devices for distribution of thermal energy INDIV-5, INDIV-5R, INDIV-5R-1 are shown in Figure 1. All modifications have an identical appearance.

Picture 1.

The design of devices for distributing thermal energy of electronic INDIV-5, INDIV-5R, INDIV-5R-1 is a non-separable plastic housing with transparent window display on the front wall. The temperature sensor is located either inside the housing next to back wall and is connected to a heat conductor, pressed during installation to a heat-receiving metal plate made of aluminum alloy, or on the fastening washer of an external cable 1.5 or 2.5 m long. The heat-receiving metal plate is equipped with holes for fastening to the surface of the heating device. The INDIV-5R and INDIV-5R-1 versions have a built-in radio module (transmitter) for transmitting recorded data to the system radio network via unidirectional radio communication (wireless M-Bus compatible with EN 13757-3 and EN 13757-4 standards). The INDIV-5R and INDIV-5R-1 versions differ in the composition of the installation kit.

Electronic devices for distribution of thermal energy INDIV-5, INDIV-5R, INDIV-5R-1 include a power source and a microprocessor with a quartz oscillator that measures the resistance of the temperature sensor, the necessary calculations and control of the alphanumeric liquid crystal display.
