High utility prices are forcing tenants to install heat meter in an apartment. For all calculations, these devices reduce costs and save money for the family budget. Payments in most cases, is charged according to the established norms, but real consumption is substantially less. Counters help owners pay monthly only on the fact of consumption. The real savings reach 40-50%.

## The advantages of using heat meters

Tariffs are established on the basis of averaged indicators of consumption, which are often more than the actual numbers. If you set the heat meter for heating for the apartment, it will be possible to monitor this expenditure and to regulate the temperature in the room at any time of the year.

metering devices will allow each month to take readings and pay for only the amount of, which was used to heat the dwelling.

We draw the attention of consumers, that 2018 , every individual meters must be calibrated with the obligatory submission of the results of the verification of the Federal Information Fund on assurance of measurement when ROSSTANDART. URL http://www.fundmetrology.ru/default.aspx

The real benefits of using counters:

- Manual or automatic regulation of temperature in the apartment.
- Setting the heating system to the specific needs.
- Simplified diagnostics and maintenance.

When using counters makes sense to install thermostats to regulate temperature. In addition to the savings they help to create the most comfortable conditions for all family members. This is especially true for spring and autumn, when long kept warm weather.

Outset, that the most profitable option is the use of heat meters when the horizontal layout of pipes with one input and one set of accounting unit. As a rule these are modern buildings.

Installing heat meter especially not bring savings, but it allows you to control and save a reasonable amount of heat consumed. If simple words: reduction of the room temperature by 1 ° C (This can be done using the thermostat on a radiator) can reduce heating costs by 5-6%.

## The main types of heat meter

The design features and the type depends on how much the meter for heating. The apartments are usually used more than one device, and a set of. It consists of the following elements:

- thermal sensors.
- electronic components, counts the number of heat energy consumption.
- devices, controlling the flow rate and pressure.

supplied is adjusted for each object individually. Professionals need to perform calculations and assess the condition of the heating system, counters to work properly.

On the application of accounting tools are divided into two main types:

- Brownies (set a private home or commercial facility).
- apartment (calculated individually on some hosts in an apartment house).

In private homes the system often is complex and ramified, therefore required sensors and other devices a set. On this depends the value of the counter for heating in the apartment for a long period of operation.

The principle of operation is dependent on the design features. They are divided into several main varieties:

- electromagnetic.
- mechanical.
- ultrasound.
- vortex.

They have the technical features and characteristics, suitable for certain applications. Devices to cope with the tasks in full in homes or other facilities.

## Design features metering devices

Modern counters on the radiators in the apartment are connected, depending on the type of. Heat flow measurement is carried out in several ways - turbocharged, or electromagnetic eddy.

Design features metering devices:

- Passageway small diameter - no more than 20 mm.
- Heat Measuring range - from 0,6 to 2,5 m
^{3}/time. - Heating medium - water.

Such devices are often found in apartments, where owners want to measure the consumption of heat energy. Utilities often the temperature is brought up to standards, but require payment in full. Payment heating in the apartment on the counter will help save money.

All the necessary calculations manages to obtain due to the interaction of two elements:

- thermal energy calculator.
- Counter hot water consumption.

Together they help to obtain the necessary data. Devices are installed on the heating system without any complex manipulation.

**Work principles**

Many are beginning to use heat meters on the heating in the apartment, How does such a system is not all clear. The principle of operation can be described as follows::

- Thermal computer is connected to the water meter.
- The temperature sensor is connected via two wires to the calculator.
- Wires are connected to the supply pipeline and withdrawing.
- The device records the amount of coolant flowing (water).
- Heat meter produces heat consumption calculation.

The principle of operation of the device based on the temperature difference Registered incoming and outgoing coolant. As a result, it manages to learn, how much energy is received directly on the heat sink. Techniques fully tested, therefore give accurate results with an error of no more than 1-2%.

To get the most accurate results, it is important to choose the right and connect the equipment.

Experts install heat meters in an apartment with a vertical wiring, and connect all the devices properly. These additional counter attached to the existing water metering device, and using the temperature sensors to the existing wire line.

work especially:

- Taking into account the volume of hot water, entering the heating system.
- Fixed temperature in the incoming and outgoing pipe.
- Calculate the amount of heat, which received radiator.

This is the easiest way to find out the volume of heat consumption. Specialists should be checked, how much heat meter for apartments, meets all standards.

### Electromagnetic heat meters

Electromagnetic heat meters - one of the most convenient and accurate instrument for large apartment buildings. The principle of operation is based on electromagnetic induction. Inside the device are magnets, creating a magnetic field, through which, in turn, passes the heating medium. Since water is an insulator, the electric current is generated. The higher the speed of the fluid passageway, the stronger the current. Special devices are fixed the indicator and calculated heat volumes.

Electromagnetic produce heat meters calculating heat capacity and thermal energy on the basis of data of a volume flow and the volume of coolant, temperatures on the forward and return flow with the specific heat of coolant changes when changing the temperature difference at the inlet and outlet.

The operating principle of an electromagnetic counter:

- The basis of the design of the magnets, forming a magnetic field.
- When the water passes formed electric current.
- Special devices read current characteristics and calculates the volume of fluid, passed through radiators.

The main advantage of the electromagnetic interference is considered to be the minimum in. They do not require significant intervention created by the heating system and do not affect the water pressure in the pipes. The price is quite high electromagnetic heat meter.

### Tachometric heat meters

Devices of this type are the most common and affordable. The principle of operation is quite simple, and the basis of design of mechanical impeller. In some cases, a small turbine.

The operating principle of the following:

- The device is switched to the heating system.
- heat transfer agent (hot water) or passes through the turbine impeller.
- The blades begin to move at a certain speed.
- Depending on the rotational speed calculated volume of hot water.

Installation of individual heat meters with additional elements is performed in the apartment - pressure gauges and resistance, thermometers and flowmeters. Together they create a system, working for a long time, and taking into account the volumes consumed coolant.

In mechanical heat meters, there are some disadvantages:

- The need to use sewage water filters.
- A noticeable pressure drop (hydraulic losses).
- Sensitivity quality of the coolant.

Hard water shortens the life of the instrument. Experts recommend installing such elements only in the stable and high pressure systems, that were not noticeable loss.

Devices of this type are sensitive to operating conditions, so it is important to observe all instructions for the installation. In apartment houses additional resistance may occur on heating batteries, affect the accuracy of the final results. Counters are also sensitive to the coolant. A large amount of iron in the water distorts the calculation of the heat for heating an apartment or house.

### ultrasonic meters

devices, using an ultrasonic measurement technique, more expensive and complex. They help to comply with the rules on the heating in the apartment, and calculation accuracy is highly. The principle of operation is based on measuring the propagation velocity of ultrasonic waves through the coolant. Counter consists of a transmitter and receiver, which must be properly installed.

- The emitter and receiver are placed opposite to each.
- Ultrasonic oxen constantly pass through the heat transfer medium in the pipe.
- passing speed varies depending on the volume of water.
- The instrument automatically calculates flow rate.

On the basis of evidence received manages count the amount of heat energy consumption.

Devices of this type are popular and recommended to the Housing . The design is good because it does not affect the water pressure. The accuracy of measurement remains at a high level, since almost no factors, affecting the characteristics measurement. The only essential requirement is to set a sufficiently long sections of pipeline. The ultrasonic method is sensitive to water quality - the dirt and scale change readings.

Ultrasonic flow meter of the heat meter is in the form of a smooth measuring channel, of the complete receiver and transmitter of the ultrasonic signal, - time of the pulse is fixed calculator for determining the flow and the medium flow rate in the heating system. No moving parts, operational reliability, resistance to pollution, high accuracy measurements at low flow rates - the characteristics of ultrasonic meters for apartment heat metering.

Price models of ultrasonic heat meters on the heating system is 5-37 thousand. rub.

If you plan to raschototopleniya custom counter in the apartment, you must sign a contract with the utility service. To operate the instrument developed specifications, and the installation is performed by qualified specialists. After installation, the representative of the housing office or the HOA be sealed with metering device, and only in this case, the management company will take evidence.

## How is the calculation of the heat meter in an apartment

To information on the calculation of the amount of payment for heating was more understandable, we look at each method of charging separately, using a particular formula is based on a specific example,. When you select a calculation option, you must pay attention to all components, which define the method of calculating.

### calculation №1
