Gas meter

A gas meter (obsolete or colloquially referred to as partial gas meter or gas meter ) is a measuring instrument for determining an enforced in a given time gas quantity. Gas meters are mainly used in the field of gas supply to use, but also for the exact amount determination in laboratory tests are used. The detected by the gas meter unit is the cubic meter in operation, which will be converted to billing in standard cubic meters.

Gas meters are made depending on the technology of mechanical or electronic devices to detect the enforced gas stream and mostly a counter.

Gas meters that are used in commercial operations, are subject to mandatory verification. In the Eichordnung the respective periods are fixed, after which the gas meter of a recurring calibration are to undergo.

For the remote meter readings, there is the possibility of equipping gas meter with interfaces. This may even happen retrospectively from the manufacturer or sporadically. For gas customers with normal domestic gas consumption structure, the possibility of remote readout is not used in the rule. In the commercial arena, that is, with larger gas consumers such as boiler plants, the use of a potential- free contact for further processing of the measured cubic meters is common in gas meters.

If the gas pressure at the service connection is more than 23-25 ​​mbar overpressure, most meters a gas pressure regulator is still upstream of (a special pressure reducer), which reduces the high pressure of the gas system.

The first gas meter constructed in 1816, the Briton Samuel Clegg.
