Atmos ® - Diaphragm gas meter
Product Overview:
Two-pipe Diaphragm gas meter G1.6S | G2.5S | G4S
Solid build quality high accuracy safety and a series of advanced techni-cal details make the Atmos@ diaphragm gas meter a high-grade measu-ring instrument. The Diaphragm gas meter is available in sizes G1.6 G2.5 and G4. The meter is characterized by precise measurements a constant measuring stability a long life and high reliability. Thanks to the use of high-grade materials the diaphragm gas meter is resistant to corrosion.
The gas meter is suitable for various gas media. The integrated calibration system coordinates the movement of the valves in relation to the optimum gas flow.
The excellent linearity of the error curve is guaranteed even at low flow rates. Due to the optimum rotating characteristics of the valves the Qmin value remains stable and the gas meter is resistant to contamination.
The Atmos diaphragm gas meter meets the requirements ofthe EN1359:1998/A1:2006 and OIML R137-1 (2012) standards.
