Gas meters are technical devices specially designed to measure the volume of gas that passes through a gas pipeline for a certain time period. In other words, these devices are used to account for energy consumption. Gas meters help to keep records of consumption in an efficient way and provide an opportunity to save significant money. Like any other measuring devices, these devices undergo a mandatory examination to determine suitability. Primary verification of gas meters is carried out during production, and periodic verification is carried out during direct operation.
Modern devices, according to their bandwidth, can be divided into three main categories. The first group includes industrial devices used by large enterprises and installed on large gas pipelines. The throughput of such devices is about 40 m/h. The second group includesvariety of household appliances. Such gas meters are used, as a rule, indoors. For example, in office buildings or apartments. The throughput of devices of this type does not exceed 6 m3/hour. The third group of devices includes household appliances, mainly used at special gas distribution stations. Municipal meters are distinguished by a rather high throughput, starting from 10 m / h. Today, such devices are most often installed at gas stations.
However, not only throughput can underlie the division of gas meters into classes, but also their principle of operation. The most unclaimed at present is the drum gas meter, which is used, as a rule, in research centers and research laboratories. The principle of operation of such a device is very simple. The drum, which rotates with the help of gas passing through it, activates a certain mechanism, which is connected to the counter. The second type is a vortex counter, which is based on the calculation of the frequency of occurrence of vortex flows around a given streamlined object (using a gas flow).
One of the most common today are devices of the third type - membrane gas meters. In this case, the basic principle of operation lies in the special moving parts that are the constituent elements of these devices. The gas entering them is divided into certain fractions, after which it is performedproduction and summation of all necessary readings.
And the last, fourth type is the rotary or RVG gas meter, which was developed due to the increase in the variety of gas equipment. The principle of its work is extremely simple. There are two rotors (or more) inside the device. It depends on the purpose of the device. The gas passing through them transmits certain mechanical vibrations to them, and all data is automatically recorded in memory. It is one of the most versatile and user-friendly devices of its kind.
Those or other types of gas meters are used everywhere in the modern world. When buying these devices, first of all, you should take into account the amount of energy consumption and for what specific needs this device is required. It is these indicators that will help you better navigate the variety presented and choose the right gas consumption metering device.
