Product DATASHEET - ZENNER - Atmos ® HP Diaphragm gas meter - HP G4A

Sizes
■ HP G1.6A : 0.016 m3/h to 2.5 m3/h
■ HP G2.5A : 0.025 m3/h to 4 m3/h
■ HP G4A : 0.04 m3/h to 6 m3/h


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 high measuring range enables precise metering for flow rates from 0.016 m³/h to 6 m³/h.  

Solid build quality, high accuracy, safety and a series of advanced technical details make the Atmos® diaphragm gas meter a high-grade measuring instrument. The Diaphragm gas meter is available in size G6.
