Diaphragm Gas Meter with Aluminum Case

Two-pipe, Temperature compensation, High accuracy and adaptability

This diaphragm gas meter features a solid build quality, an outstanding accuracy and exceptional safety performance. It is available in sizes G1.6 and G2.5 with the external case made of a die-cast aluminum, ensuring the diaphragm gas meter is corrosion resistant with a service life of up to 25 years. This meter also features precise measurements, a constant measuring stability, and an excellent reliability.

The integrated calibration system plays a key role in coordinating the optimum gas flow. Even at low flow rates, the extraordinary performance of error curve is guaranteed. These diaphragm gas meters are resistant to contamination with an excellent stability of the Qmin value thanks to the optimum sliding characteristics of the valves.

This gas meter can be used for measuring various gas media like natural gas, town gas, liquid gas, biogas, methane gas, and other gas types.
