If you are tired of average gas consumption rates "in the whole country," and you want to save honestly earned personal funds, then it's time to take care of installing a gas meter. Like any metering device, the gas meter and its installation have characteristic features.

Strict controller - gas meter
The accounting instrument, which is designed to measure the amount of gas flowing through the gas pipeline, is a household gas meter. Therefore, the meter is used for apartments and private houses equipped with mini-fuel. In most cases, gas communications and meters are set for a significant period of operation.
Before choosing and installing a counter in the apartment, you need to think about the safety of its performance and durability. Installation of a gas meter is a regulated activity that is controlled by the relevant authorities. The process of installing the gas meter will begin with a visit to just such coordinating organizations. So, the time has gone ...
Principle of operation of gas meters
As is known, an invisible gas, thanks to which we are able to prepare food, is a mixture consisting of certain components with specified properties. Therefore, the process of calculating the gas mixture is constructed according to the laws of physics.
According to the principle of operation, gas meters are divided into groups:
• turbine
• vortex
• rotary
• membrane.
For domestic needs of the population, gas meters of rotational and membrane type are used.
Rotary gas meter is based on the principle of counting the past gas volume in proportion to the number of revolutions of the rotor. The portion of gas cut off between the wall of the measuring chamber and the rotor is a quantitative unit. When the rotor rotates through a mechanical transmission, this information is transmitted to the counting mechanism, where the actual amount of gas is actually accumulated. The quantitative value of the count is Qmax. For the household sector Qmax. is from 4 to 10 m3 / h.
Principle of operation membrane counter based on the short-term displacement of thin moving membranes. In gas chambers, in the presence of a gas mixture, these membranes move into the device, which, through a mechanical transmission, activates the counting mechanism. Membrane-type meters are used for maximum gas flow rates Qmax. from 2.5 to 100 m3 / h.
The device of the household gas meter is shown in the video.
The general classification of accounting gas appliances is based on the volume of gas consumed. So the gas consumption of the average plate with 4 burners is 1.56 m³ / h, for the gas column - 2.50 m³ / h.
Industrial gas meters are produced taking into account the direction of the gas flow. Therefore, acquiring a gas meter for the apartment, it is necessary to take into account the location of the gas pipeline and the stove in the kitchen.
Rules for installing the counter
Before starting installation work, you must contact the city gas utility. This procedure is necessary in order to find out all the conditions and details of the meter installation. Acquisition of a gas meter can be done independently, connecting a familiar professional specialist.
As an alternative - the purchase of a meter in the gas economy and installation of its specialists farm. In this case, you can even save a few on buying a counter, because gas specialists are interested in this acquisition.
Installation of the gas meter is carried out only by specialists having license rights for the installation of this type of equipment. You are looking forward to, when will the features of the national installation counters come?
Features of the installation will come immediately after you filed an application to Gorgas. So, the next stage of installing the meter will be the submission of an application to the city gas utility. To the application, certified by a personal signature and the filing date, a photocopy of the technical passport for the living space and a certificate on the absence of arrears on the energy carrier for the current month of service are attached. After submitting the application and registering the meter, you will be assigned the day of the gas specialist's visit. Visiting a specialist should determine the technical possibility of the subsequent installation of the meter. In addition to such a survey, you will be told the price of the installation.
On the appointed day, the gas meter will be installed and installed by gas specialists.
Installation of equipment depends on the particular design of the particular model and the location of the gas pipeline in the kitchen.
Features of installation of gas meters
The gas pipeline can be laid at the level of the connecting pipe. The shut-off valve can be located on the side of the plate at a distance of 200 mm. In the case of overhead wiring, the shut-off valve is installed on the descent. The gas meter must be visible and must be located away from the plate.
The permissible installation height is 1.5 m from the floor. Installation and installation of gas appliances is regulated by SNiP 42-01-2002 and SP 42-101-2003. According to paragraph 6.47 of SP 42-101-2003, installation of meters is provided based on the conditions of convenience of their installation, maintenance and repair.

Gas meters can be installed with rubber hoses. Rubber hoses must not enter the heating zone of the appliance. Installation of meters provides the following convenient conditions for maintenance or repair.
Such conditions are regulated by the operating documentation of the manufacturer. It is recommended to install meters outside the zone of moisture and heat emissions in well-ventilated areas.
And we have gas in the apartment, and you
After the successful completion of the installation work, the owner of the apartment and the new installed meter receives the installation certificate and a settlement document intended for sealing the meter. And here again there are "features" of installing gas meters: you can not start using gas until seals are installed.
The installation of seals on the counter is made by specialists. Payment for gas, according to the meter, is made after the installation of seals. The life of the meter depends on its brand. In 10-15 years you will have to take the meter for another verification.
Of course, you will be lucky if the gas meters were installed and registered earlier. In this case, the gas meter can not be replaced. If the meter meets all parameters and is in working order, then it will be sufficient to conclude a contract with the organization. However, all formalities for the correct execution of documentation must be observed.
And now, at last, behind two weeks of waiting, and you are a happy owner of a gas meter in your apartment. The membranes and rotors of the counters are waiting for the first portion of the explosive mixture called "gas."
