How to install a gas meter yourself

Gas accounting allows you to understand who and for what you pay monthly. If you have not installed a gas meter, you will pay for each family member that is registered on this housing, regardless of such a factor, whether you use the entire limitable gas volume or not. If you put the gas accounting device, you will pay exclusively for the used energy carrier. Consumer experience shows that monthly payments for gas use after installing the meter will be reduced by 30 50%. Today we’ll talk about how to install a gas meter yourself and how to choose the right device.

The purpose of gas meters

In the private sector today, a large number of houses are heated by gas. In our country, tariffs for this type of energy are rapidly increasing. In order to keep an accurate record of this resource, you need to know the amount of gas consumed and control its costs. For this, there are special gas meters.

On average, 1000 cubic meters of gas are consumed per month, depending on the quadrature of the heated room. In the warm season, gas consumption is minimized, but in winter there will be impressive amounts of payment, which in general makes the installation of a gas meter to save resources.

Installation in the houses of the owners of the gas metering device is not a luxury, but a real necessity. Using a gas meter, the amount of spent liquefied or natural gas is measured. That is, with the help of this device, you can keep records of energy resources, as well as stimulate consumers on their savings.

The measured gas meters are Butane, propane, natural gas, as well as other non -aggressive and in their chemical composition heterogeneous gases. Gas consumption is most often measured in cubic meters per hour. For example, the costs of buying the device itself and the cost of installing a gas meter on average pay off during the year.

Such a gas metering device can be installed in the most gasified room or the premises of the gasified building, if there is ventilation in it. Also, the installation of meters is allowed in a room that is adjacent to the gasified, and if there is an opening between them.

The counter should be far from the moisture and heat in the zone. It should be located in a well -ventilated place. Unwanted installation places are niches, as well as areas in which fresh air does not enter. If the device is installed outside the building, then it should be under a canopy or in a closet, that is, covered from external influences.

Varieties of gas meters

The need to install the gas metering device was evaluated by large enterprises and individual private individuals. At the moment, there are four types of gas meters: vortex and turbine flow meters, rotational and membrane.
The principle of action of the diaphragm (chamber, membrane) counter is based on the fact that the gas is divided into shares of volume using various converting elements, and then their cyclic summation is produced.

The advantage of diaphragm meters: low cost, prostate in manufacture, as well as quite accurate calculation even with not very large use of gas. But such counters practically do not tolerate both constant and temporary overloads.

A rotational counter is a chamber gas meter, as a transformative element in which eight -shaped rotors are used. In a rotational counter with small overall dimensions and mass relatively large passage, it also withstands certain overloads and durable. The rotational gas meter is made of expensive materials, requires thorough fitting parts, and in cost more than other counters.

Gas meters are turbine meters in which the turbine wheel is given in rotation by exposure to gas flow, and the number of revolutions is directly proportional to the gas volume that is flowing through it. The counting mechanisms of the turbine gas meter have recently been equipped with modems, with which all indications are transmitted to servers to inspection services.

Such a meter as a vortex uses the calculation of the frequency of the occurrence of vortices near the body, which is stuck on the stream of gas, the frequency of which is a proportional flow rate. In order to detect vortices, thermanemometric or piezoelectric detector sensors are used. Such advantages of vortex meters are distinguished: rather high maximum costs relative to the diameter, a wide measurement limit, especially at high pressure, low sensitivity to pollution of this measured environment. This counter also needs external electric power.

Gas consumption calculation

Gas meters in maximum throughput are conditionally divided into industrial, domestic and communal and household. Most often, the installation of household gas meters with a bandwidth of 1 - 6 meters of cubic per hour is practiced in offices, apartments, houses, as well as small furnace for accounting for gas consumption. These are usually membrane (diaphragm, chamber), less often small rotational, ultrasonic, jet devices.

Devices such as communal and household, with maximum throughput within 10 - 40 cubic meters per hour, are used to account for gas consumption with technological installations, small boiler rooms, etc. This is usually larger membrane (diaphragm, chamber), jet, rotational , ultrasonic gas meters.

Basically, industrial devices with the maximum throughput of more than 40 cubic meters per hour are used at nodes of large consumers, such as industrial and agricultural enterprises, gas boiler rooms, main networks (narrowing devices, ultrasonic, turbine, vortex gas meters), as well as gas distribution networks) (turbine, rotational, jet, ultrasonic, vortex gas meters).

The following types of marks of gas metering devices are mainly distinguished:

• G-16 throughput is from 16 to 25 cubic meters of gas;
• G -10 10 - 16 cubic meters. meters;
• G -6 6 - 10 cubic meters. meters;
• G -4 4 - 6 cubic meters. meters;
• G -2.5 about 2.5 - 4 cubic meters. meters;
• G -1,6 - about 1.6 - 2.5 cubic meters. meters.

To install the gas meter in the apartment, you need to choose the device depending on the number of gas devices used. If a gas stove with 2 burners is used in the house, which consumes about 1 cubic meter. meters per hour, then you can do with the apparatus with the marking G-1,6. In order to calculate the total fuel consumption, you need to look at the passport of each device that the gas uses. There are left and right meters, depending on the direction of passing the energy of the energy, and the choice of a certain type depends on the location of the plate and pipes in the kitchen.

The principle of operation of the gas meter

The gas meter consists of a sealed case, in which the measuring mechanism is built -in, as well as the counting device. The principle of operation of the diaphragm gas accounting apparatus for energy selected from the incoming gas is founded. Alternate gas suppression is made of working cameras when moving the diaphragm. The vulgarity of the diaphragm transforms the vulgar movement into the rotational, which is transmitted through the coupling to the reference device.

In the design of the meters there is a device with a bimetallic temperature compensator, which is adjusted when the gas temperature meter is affected. Such a compensator at gas temperatures that are distinguishable from the norm changes the volume of measuring chambers and this volume of gas consumed leads to standard conditions.

Installing gas meter with your own hands

The best option is the installation of a common house gas metering device. Of course, the price of such a gas meter is much higher, but there will be much less expenses than the installation of an individual gas meter. If you do not have such an opportunity to install a gas meter for the whole house, read on.

If you have only a stove in your use, it makes no sense to install a household counter at all. The payback period during the operation of the device only with a gas stove can take up to 5 years. But the presence of a water heater and a gas stove is already a good option. The best solution is if you have a boiler, a water heater and a stove. The recalculation time of the counter will depend on the existing gas equipment.

Application of an application to a gas organization

We must not forget that gas equipment is a product of increased danger. It follows that only a specialist who has certification should be engaged in the installation of the counter. Gas is very dangerous material so that unprofessional people are engaged in it. Thus, independent installation is not welcome.

The gas supplying organization controls the entire installation process, so that later during operation there are no problems. The sealing of meters is exclusively conducting those organizations that are allowed by law and which have special permits and licenses. After the end of work, you should issue an act on a successful operation in your hands.

The very first step is to submit an application for the installation of the apparatus in the regional gas organization. Before installing the counter, you need to consult a specialist about gas consumption in the apartment in order to choose the device of the desired throughput and the corresponding class.

In accordance with the technical conditions and requirements for installing gas meters, you need to purchase a device. The gas meters intended for apartments and residential buildings differ from each other, first of all, with a face value, that is, the amount of energy resource, transmitted per unit of time. If the apartment is equipped only with a gas stove, then the device is suitable that passes two and a half cubic meter of gas per hour.

Gas meter installation project

When installing a gas meter, one more feature must be taken into account. This is the development of a gas meter and gas equipment meter installation scheme. This project should determine the radii bending of the pipe, the distances from the counter to the heat source, as well as some other parameters. Quite often, this situation is not fulfilled, but in vain!

To choose the installation site of the counter, you must be guided by the following considerations:

• The meter is installed at a height of 1.6 meters.
• The passport of the device must indicate the distance from the gas equipment to the gas meter. If there is no such point, then the distance should be from a household plate or heating equipment (boiler, heat generator) at least 0.8 meters. From the restaurant, hob and heating stove, as well as the hob to the meter, the distance should be at least 1 meter.
• The gap should be between the counter and the wall of at least 3-5 centimeters, so that there is no corrosion damage to the metering device.
• The room itself should have natural ventilation, while the device is undesirable in the stagnant zone.
• If the counter is installed inside the room, then it should be placed away from objects radiating heat and moisture.
• The rules for installing gas meters still allow you to put the device in an open form outside the building, but still, to extend the service life and safety, the device should be installed under a canopy in a closet or other design, but it must necessarily have doors with constipation and natural ventilation. It is advisable to install metering devices under the openings in the wall.

Mounting gas metering device

After contacting the gas service, you will be made an account, after which the master will come to you and will definitely install the gas meter. At the entrance to the gas meter from the gas pipe in any case, you need to put a special filter-pile. The device can easily break if you do not install such a filter.

Remember that in the process of installing the counter, documents existing on your gas equipment (gasification project, passport) are checked so that there are no troubles, you need to put them in order in advance. After installation, you need to immediately issue a passport of the gas metering device. It often happens that the master in the passport puts a mark on the spot, but sometimes you need to contact the gas service. Next, the counter is sealing.

The specialist, the management company, after installing the counters in two copies, transfers the contract for the installation of the metering device, then the act of acceptance of the completed work is signed, also in two copies, the act of putting the apparatus into operation in triplicate, and in triplicate an agreement on the maintenance of the device accounting.

After that, the owner of the apartment goes to the DEZ or HOA and provides an act of commissioning, and then concludes an agreement to pay for a resource on the gas metering device. It will be necessary to report the indications of the gas meter to the information and settlement center once a month, after which you will be informed the amount of payment.

One of the important points of using the meter is to check the apparatus for the correct operation. The manager of the company carries out the initial check, and then this is done by the owner of the gas meter, causing once in a certain number of years (such data are indicated in the passport of the apparatus) of the representative of the standardization center and metrology, which checks the devices and makes appropriate marks in the passport of the device.
