Emphasizing solid build quality, high accuracy, safety, and a series of advanced technical performance details, the Atmos® diaphragm gas meter was developed as a high-grade measuring instrument. The diaphragm gas meter is available in G4, G6M, and WG6M sizes. The metering equipment provides precise measurements, constant measuring stability, high reliability, and delivers a long service life. We manufacture these meters from high-grade materials, giving them excellent corrosion resistance, another factor that enhances their longevity.

The diaphragm gas meter is suitable for the metering of a variety of gas types. The integrated calibration system plays a key role in coordinating the optimal gas flow. Even at low flow rates, the extraordinary performance of the error curve is guaranteed. The meter is resistant to contamination with a stable Qmin value thanks to the optimal sliding characteristics of the valves.

Our Atmos® diaphragm gas meter meets EN1359:1998/A1:2006 and OIML R137-1 (2012) standard requirements.
