Atmos^®- Diaphragm gas meter

Product Overview:

Two-pipe Diaphragm gas meter G1.6A | G2.5A

Solid build quality high accuracy safety and a series of advanced techni-cal details make the Atmos^® diaphragm gas meter a high-grade measuring instrument.

The Diaphragm gas meter is available insizes G1.6 and G2.5.

The meter is characterized by precise measurements a constant measu-ring 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 Q_min value remains stable and the gas meter is resistant to contamination.
