Technical Methods And Requirements For Gas Meter Calibration
Calibration of gas meters has become a necessity nowadays. Several methods are applied for performing gas meters’ calibration. The most common ones are:
Gas Meters – Principles of Operation
Gas meters can be divided into two categories: displacement meters and flow meters. Displacement meters measure volume directly through periodic filling and emptying of one or more measurement chambers. This is why displacement meters are considered to be volumetric meters. The most common displacement meters are:
