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 of the EN1359:1998/A1:2006 and OIML R137-1 (2012) standards.
