Diaphragm gas meters for measuring LPG and NH3 consumption

Diaphragm gas meters are reliable appliances for accurately measuring the consumption of LPG/NG in primarily residential installations but also commercial and light industrial pipework. The allowed pressure endurance limits the usability in the industrial sector, as a much higher-pressure capacity is required than what the diaphragm gas meter can handle.

Product description

Also known as a positive displacement meter, the diaphragm gas meter can accurately measure the amount of gas consumed by counting the number of cycles the internal piston has travelled due to the volume of gas passed through the chambers.

Did you know?

  • The basic design of diaphragm meters have not changed since 1843 and is commonly used in domestic gas systems due to its reliability down to as low as pilot light flow rates
  • ProSupply can upon request provide meters for high pressures up to 1.5 bar (21.75 psi)
