Zenner Atmos HP Diaphragm Gas Meter HPG1.6A, HPG2.5A, HP G4A

Zenner Atmos HP Diaphragm Gas Meter are precise measurements, constant measuring stability, a long life, and high reliability characterize Zenner Atmos HP Diaphragm Gas Meter. Thanks to high-grade materials the diaphragm gas meter is resistant to corrosion.

Zenner Atmos HP Diaphragm Gas Meter HPG1.6A, HPG2.5A, HP G4A The gas meter is suitable for various gas media. The integrated calibration system coordinates the movement of the valves about the optimum gas flow. The excellent linearity of the error curve is guaranteed even at low flow rates. Due to the valves’ optimum rotating characteristics, 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. [nbsp].

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 meter is characterized by precise measurements, a constant measuring stability, a long lifeandhighreliability. 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 value remains stable and the gas meter is resistant to contamination.

The high measuring range enables precise metering for rates m³/h to 6 m³/h.
