Compact type Diaphragm Gas Meter-MA
Two-pipe, compact, high accuracy and safety, Die-cast aluminum case
This diaphragm gas meter has a compact look, and its available in sizes G1.6 and G2.5. This diaphragm gas meter is characterized by solid build quality, high accuracy and safety. The external case can be made of die-cast aluminum case made the diaphragm gas meter resistant to corrosion with high-quality diaphragms result in long life stability- up to 25 years. This gas meter can be used for measuring gas media like natural gas, town gas, liquid gas, biogas, methane gas, etc.
The integrated calibration system plays a role in coordinating the optimum gas flow. Even at a low flow rates the extraordinary performance of error curve is guaranteed. This diaphragm gas meter is resistant to contamination with stability of Qmin value thanks to the optimum sliding characteristics of the valves.
Our compact type diaphragm gas meter meets GB/T5968-1997, EN1359:1998/A1:2006, 0IML R31:1995 standard requirements.
