Domestic gas meters: how to choose? Technical characteristics and reviews

Counters for electricity and water have long and firmly entered our lives. Now it is time for household gas appliances. How to choose the right counter specifically for your home, how to calculate the throughput, which firms produce the best household gas meters ? How to choose them and not make mistakes?

Is it necessary?

Now many argue about the significant savings when installing meters. On the one hand, some say that the installation of meters in apartments where a single stove is installed is impractical, since such a device will pay off in no less than 5 years. On the other hand, the people who installed the meters tell us about the significant savings when paying for gas. In this case, we are talking about a fairly significant figure, about 25-50%, because you pay for the amount of gas actually consumed, which, for example, is extremely beneficial for those who move to summer cottage in summer. And those who use running water heaters-columns for heating water or live in a private house, where boilers are used for heating, it is worthwhile to establish a household gas consumption meter as soon as possible. Also , the meters will help those who have more people in their apartment than they actually live in. The savings in this case will be quite weighty.

Types of counters

Now on the market there are four main types of gas meters: membrane, vortex, rotary and turbine. Membrane metering devices divide the flow into fractions and, using various elements, add up the flow. The obvious advantages of this type of meter include their low price, as well as a sufficiently high accuracy of the readings. However, the membrane counters do not withstand constant and variable loads. Most household meters currently installed are membrane type. It is worth noting at present gas meters household, technical characteristics of them have made significant steps in simplifying the installation work, and primarily this is due to the reduction in overall dimensions. The rotary type of counters is resistant to overloads, long-lived, and also has a sufficiently high throughput with small dimensions and weight. As the converter element, eight-shaped rotors are used in it. True, such a device is made of expensive materials, requires a long-lasting adjustment of parts, by itself, it is much more expensive than other types.

In turbine counters, the turbine wheel is driven by a flow of gas, hence the number of revolutions is directly proportional to the volume of the gas passed. Recently, such meters are equipped with modems for transferring information to the servers of gas accounting services.

A vortex meter needs external power, so it is not very convenient in everyday life. Similar counters can be appreciated by industrial enterprises, since their main advantages include a large range of measurements, especially at high pressures, and low sensitivity to contamination. Also, the main gradation of meters can be considered their separation in the place of installation: household, industrial and municipal. Of course, it is very conditional.

Throughput

So, you decided to purchase household gas meters for your house . How to choose the right device for you in accordance with the installed gas equipment? Let's look at the meter line and its relationship with the counter labeling, depending on the bandwidth. A gas meter installed on one device will have a mark G 1.6, that is, its capacity is up to 2.5 cubic meters of gas per hour. The G 2,5 meter passes up to four cubes of gas. Gas meter small-sized household G 4 is quite suitable for an apartment with a stove and a column, its capacity is up to six cubic meters. And so on. The counter with the number 6 in the marking will miss up to 10 cu. Meters, with a figure of 10 - up to 16 cubic meters. And, finally, there is a counter for private houses with a large number of devices - G 16, with a throughput of up to 25 cubic meters of gas.

note

Acquiring household gas meters, people's opinions must be taken into account. Users are talking about errors in the operation of the equipment. Collide with them already at the stage of installation of meters or after a conversation with representatives of gas services. Before you buy a meter, pay attention to the location of gas appliances and the entire pipeline, as manufacturers create meters with different directions of gas. Residents of private homes should think about purchasing a counter with a thermocorrector. A mechanism with a bimetallic expansion joint is installed in the structure. At a medium temperature different from normal, it changes the volumes and leads them to normal conditions. This, in turn, significantly reduces the meter reading. All these conditions will be met if the meter is installed on the street and subjected to temperature influences.

Counters "Grand"

As the basic installed now counters, perhaps, it is possible to allocate some successful models. Household counters of gas "Grand" are produced in a full line - from households with a minimum throughput to models with a throughput of up to 25 cubic meters. Meters with thermal correctors. One of the main advantages of the devices of this company can be considered the possibility of installing it in both horizontal and vertical position, which, of course, is convenient in most kitchens of our country. The service life of the device is about 12 years. The period of the intertesting interval is also 12 years. In the meter body, a battery is installed to operate the electronic display. For the installation of this gas metering device, it is not necessary to perform welding operations on gas pipelines, which will significantly reduce the cost of work. In addition to technical advantages, the manufacturer also took care of the aesthetics of this device. Counters "Grand" are issued in three basic colors (white, orange and black). Feedback from the owners of the device suggests that such household gas meters (electronic mechanisms) are extremely convenient from the point of view of placement and significantly save gas costs. At the same time, installation costs pay off within a relatively short time, of course, if you have at least two devices installed.

Counters "Betar"

Direct competitors to the "Grand" can be called gas meters, produced under the brand name "Betar." This device is also quite compact, small overall dimensions allow you to place it without disturbing the aesthetics of the room, and at the same time observe all the necessary standards. The meter is made of plastic, it has a trapezoidal shape. Household gas meters "Betar" operate approximately in the same temperature range as the "Grandees". Also, they install the appropriate battery, but here lies the difference. The first models of "Betar" were equipped with an element, which after 5-6 years was out of order. In any case, it is with such feedback that you can find on the Internet about the first models of accounting devices of this company. In other respects, as for the claimed service life and the calibration interval, the "Betarov" performance is not inferior to the parameters of the "Grand" counters. To the obvious advantages of this meter is its "immunity" to various electromagnetic influences.

Application for installation of the meter

So, you decided to install on your appliances gas meters household. How to choose an organization to avoid unnecessary problems? It is worth remembering about the dangerous properties of gas and in this case it is not worth saving. It is simpler and more convenient in this case to apply to a regional gas company. This will save considerable time and effort, since in most regions the operation will be performed on a turnkey basis. A specialist will conduct a survey on which device will be more profitable for you to determine what bandwidth will be needed for your meter, where and how it will be located.

Installation rules for the gas meter

When choosing a location for installing the device, several basic rules should be followed. So, you can not install meters for appliances that emit heat and moisture. The installation height above the floor level should be at least 1.6 meters. The distance from the wall to the counter should be at least 5 centimeters. The room where the meter will be installed must have natural ventilation, and it should not be installed in a stagnant zone. Well, perhaps, one of the main points - the distance from the gas-using equipment to the meter. If the passport does not specify a given distance, then a general standard should be adopted. Its value is 0.8 meters.

Installation of household gas meter

After performing the installation of the device, the gas service employee will seal the meter and transfer all necessary documents to the monitoring organization. It is also necessary to issue a passport of the meter to maintain guarantees. That, in fact, everything. The gas flow meter is installed, sealed, you have already begun to save. We hope that we were able to answer all your questions about what household gas meters exist, how to choose what you need, how and by whom it should be installed.
