The choice of the gas meter
The rate of growth of gas prices are onpeople are much more convincing than the government regulations on mandatory equipment of all kinds of housing metering devices. The fact that the payment of water on the counter brings considerable economic benefits could be no doubt, but counting "kopek" source of energy is not too eager. Forward-owners of communal housing have already purchased and implemented in network devices, taking into account the consumption of natural gas wealth. Now the installation of the gas meter in the apartment was needed not only thrifty owners, but to all citizens of the country and the state, issued a decree to consider the costs of all resources.

The principle of operation of the counter and the selection rules
Depending on the method of activation of countablemechanism of gas flow meters are divided into four classes. Leaving aside the rotary, turbine and vortex machines are designed for businesses. Consider the device membrane-type gas meter (also known as a diaphragm or a chamber) used in the domestic utilities.
As the device reads the information
For those who want to install a gas meterapartment information on the work of the membrane system will not be superfluous. The device consists of the original camera with alternately opening "curtain". Shutters structurally related to the cross-rod mechanism.
- First, the gas fills the cavity of the first chamber, by flooding it causes a deformation of the diaphragm.
- Aperture shutters transmits motion damper, which in turn opened by passing a portion of the gas in the next chamber, and tightly closed, sending the contents of the next cavity.
- The mechanical impulse from the movement shutters overlooking a portion of the gas is transferred to cross-mechanism.
- The movement of the cross signals attached thereto "sprocket", rotating in one direction only.
- "Zvezdochka" says counting device, as portions of the gas passed through the device.
Note. All components of the device are made of aluminum or plastic, because the magnet on the gas meter readings act meaningless.
Arriving on the nozzle into the gas appliance on the basis of displacement sequentially moves from one cell to another. After the process is repeated cyclically.
How to choose a gas meter?
Classification of accounting devices is based on the volumegas consumed per hour. To determine this parameter should study the technical characteristics established in the apartment units. Consumption average gas stove with four burners of 1.56 m³ / h, gas water heater consumes 2.50 m³ / h. The sum will tell the total amount, according to which the selected device model.
Council. Buyers, find out how to choose a gas meter, you should know that the supply of gas at different options to address the devices can be made with the left or right side. When choosing not forget to pay attention to this aspect.
According to the labeling:
- the device with the designation G-1,6 can skip and count 1,60 - 2,50 m³ / h;
- G-2,5 skips 2.50 - 4.00 cubic meters;
- G-4 from 4.00 to 6.00 cubic meters.
Features G-6, G-10, G-16, etc. determined by the same principles.
Attention. Be sure to check the date of issue of the acquired unit, as gas meters calibration interval is calculated not from the date of installation, and the date of manufacture. If, after factory testing took longer than necessary for the verification of the following years, the owners may have problems with the service of gas supply operation.
Please note that the deadline for verification of old gas meters SG sample was 5 years old, the new generation of counting devices interval between verifications shall be calculated 12yu years.
Operating conditions of gas meters
Terms of installation of the gas meter determines the degree of filtration device passes through a substance - less than 100 m, which should be provided Gorgaz.
- The room temperature and the temperature of the gas passing through the counting device is determined by the minimum and maximum limit of -20º + 60º.
- The meter is able to withstand a short-term increase in consumption by 20%, without any problems will take increasing regulatory pressure to 10%.
- Before tapping point device to the gas network is not necessary to have a straight section of the pipeline.
You can set the device vertically orhorizontally. The main condition to check gas meter was not difficult and can be carried out with a representative of the company which supplies certain periodicity contract.
Specificity and units installation rules
Installation of the unit should carry out the organization,has licensed the right to the work. This can be not only a service Gorgaza. Before installation, it is reasonable to ask, how much is the installation of the gas meter, implemented by different companies. Just do not forget that the standard rates in any case will be adjusted in accordance with the design features of the device, as well as to the location of gas appliances and piping.
- The process of equipping the gas network accountsdevice anticipates the submission of an application in the RPE (point of energy saving), the urban gas facilities. The application you need to make a photocopy of the registration certificate in the living area, and a certificate of timely payment of gas introduced in the last month.
- After the application is assigned a specialist visit, time, which is to determine the technical feasibility of the installation of the device and call the exact price if you need extra work.
Council. Gaskets, flexible hose and the device itself is better to buy your own. The cost of equipment and devices, purchased in establishing the organization, often seriously overstated.
- Then all the work is done gasman,thorough knowledge of how to set the gas meter. The owner should be sure to take in implementing the act and the settlement document for further oplombirovki accounting device. To pay for gas according to meter reading owners will be able only after the installation of seals. From that moment on them rests the responsibility for the violations and damage as seals and instruments.
To take readings of the meter should be monthly. At the gas supply company has the right to monitor how well made the transfer of gas meter readings homeowners. The normal frequency of monitoring the gas industry 1 every six months. If in doubt about the authenticity of the information the company may appoint examination. If you find a violation on the part of the user, he will have to pay for dismantling, installation and testing. Doubts about the veracity of the testimony of the owner must also dispel the expert. But the maintenance associated with the periodic verification is made by the organization which established a counting device.
Who know whom to contact and howput the gas meter, probably found the article interesting answers to their questions. Self-embedding devices in the loop, transporting an explosive substance with a toxic effect, it is impossible. But the rules of operation, installation and workflow gas industry services to the customer need to know.
