Wide-range Diaphragm Gas Meter
Two-pipe, wide-range (0.016m3/h to 6m3/h), accurate and stability
This diaphragm gas meter is featured with wide metering range, precise measurement and high reliability. High measuring range lead to the precise metering results. The external case can be made of powder-coated galvanized steel or die-casting aluminum made the diaphragm gas meter resistant to corrosion and hig-quality diaphragms result in long life stability- up to 25 years. This gas meter can be used for measuring various gas media like natural gas, town gas, liguid gas, LPG, biogas, methane gas, etc.
The integrated calibration system plays a major role in coordinating the optimum gas flow. Even at low flow rates, the gas meter still can do a excellent job with accurate measurement.
This diaphragm gas meter is resistant to contamination with stability of Qmin value thanks to the optimum sliding characteristics of the valves.
Our WG2.5S diaphragm gas meter meets GB/T5968-1997, EN1359:1998/A1:2006, 0IML R31:1995 standard requirement.
