Heat meter for battery: the principle of operation. Installing the heat meter on the battery

Many people are forced to install a heat meter on the battery due to large utility bills, most of which is for heating. To the high tariffs and at the same time to the cold batteries there is a lack of proper thermal insulation, installation shortcomings and heating systems that have served their time. Devices that account for the consumption of related services, allow you to pay only what was actually received. Since the accounts specify the data of a house-count meter, calculations are made on the basis of square meters of housing.

What you need to know

When deciding on the need for such a device, it is worth remembering that it is not a means for economy, but it makes it possible to pay only current consumption, rather than a common one, divided into all tenants. The heat meter for the battery in the apartment marks any fluctuations in the temperature regime and allows you to keep a record of consumption only under the condition that the thermostat is operating properly and the node is correctly executed. If before leaving home, for example at work, to reduce the temperature by at least 1 ° C, then by the end of the month you can see an economic bonus of 6%.

Required documents

It is also worth remembering that the installation of such a device carries a lot of difficulties, and, in addition to collecting a certain list of documents, unforeseen expenses may arise . The self-preparation of the documentation will take several weeks, you will have to visit the relevant institutions and collect the following:

• Design data of the heat consumption device;
• The technical conditions set by the authority providing the building with heat;
• Permission from the building's balanceholder.

Additional coordination of all calculated data with the set values is required. Installation is carried out in accordance with all project information, after which an agreement is concluded with the energy supplier on the basic documents for payment based on data from the apartment meter. Then the representative of the appropriate authority draws up the certificate of delivery of the installation and registers the device.

As it may seem at first glance, it does not cause any special difficulties, but each of the items may imply an additional list of documentation, and each of them can be delayed up to two weeks.

Features

Prices for individual accounting devices start on average from 4000 rubles. More expensive ultraviolet, more modern mechanisms, but their installation is not always rational in the public conditions.

A vertical heating circuit is characterized by the attachment of several sections to one riser. In this case, one riser pipe goes down, and the other - comes from above. Pipes in the horizontal scheme come out from below and come back. This wiring has become most common in modern homes, although its arrangement is more expensive than the vertical version. Both types of breeding, one way or another, concern water supply.

Heat meter for battery: operation principle

Such an individual device is envisaged for rooms having a horizontal piping scheme. Its principle of operation is based on the temperature measurements at the entrance and exit into the system and the subsequent calculation of the energy spent by the heat carrier. Expense data are recorded for several approaches, after which the received indicators are processed. In new devices there is an exit function to the PC and saving values for 10 years.

The heat meter for the battery has in the design a flowmeter, 2 temperature sensors and a calculator. The latter can have an autonomous or external power supply. For the first option, it is necessary to connect to a 24 V power supply and, accordingly, the installation of an energy transformer, the second model has a short service life of the supply elements and sometimes an insufficient length of wires.

Varieties

The type of device is determined by the installed flow sensor, which has three variations.

The work of ultrasonic flowmeters is based on the use of a signal receiver and emitters with an opposite arrangement. Externally, heat meters for a heating battery are presented in the form of a hollow section of the pipeline with equipment in the form of an LCD display, sensors, thermal calculator and thermometers. To count the data, you just need to click on the button. Such a device allows you to take measurements while away from home, while it does not form hydraulic pressure and is informative. Among the shortcomings, buyers note the need for UPS-connection with an unstable flow of electricity and the possibility of incorrect data with a turbid or air-cooled coolant.

The electromagnetic heat meter for the battery is a hydrodynamic generator of small dimensions. It is characterized by accurate indicators provided that it is correctly installed. The main disadvantage is the formation of salts on the electrodes, which reduces the accuracy of measurements, which are also affected by electrical appliances.

The meaning of the work of mechanical meters is as follows: a small turbine is introduced into the liquid, where it rotates depending on the flow velocity. Such devices have the function of receiving remote signals to determine the current flow rate. Also, the heat meter for the battery is characterized by ease of use, budget cost and power from its own source - batteries. It is possible to obtain greater savings by installing a regulator with a board and valves. The drawbacks include the lack of the ability to read data at a distance and store information received in a day, and they form pressure in the system and are subject to wear, like any other mechanism.

Installing heat meters on the battery

The installation of the device depends on its functionality and does not cause any special difficulties. On the system, it is fixed to the feed and approaches the feed tap. Then, two stopcocks are placed, one on each side of the device. During the movement of water, a grid for filtration is placed.

Connection of the device is authorized to be carried out only by the company, which has a special permission to conduct similar services. Experts conduct a phased installation, inspect properties, register the unit and put it into operation. It is worth noting that many organizations involved in the installation of devices perform subsequent maintenance. They also undertake the verification.

Saving

If there is a high-quality thermal insulation in the apartment and a constant temperature around 25 degrees Celsius, with the help of the regulator it is possible to change the heating mode to a more comfortable one, and a much smaller amount of gigacalories will be spent. With the help of shut-off valves, regulation and control of the supply of thermal energy to the radiators is carried out. A noticeable difference in accounts arises even at one turn of the crane.

The apartment heat meters for the battery are installed mainly on a horizontal heating system having a separate section of the floor. Of particular importance is the location of the living space. People living in corner apartments on the last and first floors, provided a comfortable temperature range of 15 to 22 degrees Celsius, will not notice a special budget saving.

Selection

Of particular importance are the degree of error, the amount of incoming data and their archiving. When selecting the main criteria, the energy input circuit and the type of coolant become. In this case, it is worth paying attention to the maximum data that are known to the experts of the appropriate authority. The choice of a certain option is determined by the connection of the device to the pipe and the dimensions of the pipeline system. The heat meter for the battery, the feedback on the various models of which are very different, usually has a smaller outlet size with respect to the pipes, which leads to an increase in the hydraulic pressure at the installation site. This can affect the degree of error.

In the device model, the important parameters are the type of DHW device, thermal inputs and possible pressure drops. This indicator is mostly small.
