Zenner Atmos Wide-range Diaphragm Gas Meters

The meter is characterized by precise measurements, a constant measuring stability, a long life and high reliability. Thanks to the use of high-grade materials the diaphragm gas meter is resistant to corrosion.

The Atmos wide-range diaphragm gas meters WG2.5S is available in size G2,5.

Description

The meter is characterized by precise measurements, a constant measuring 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 sliding characteristics of the valves the Qmin value remains stable and the gas meter is resistant to contamination. The high measuring range enables precise metering results. The Atmos® diaphragm gas meter meets the requirements of the EN1359:1998/ A1:2006 and OIML R137-1 (2012).

Zenner

ZENNER gas meters impress by the solid processing of high-quality materials combined with a large number of technical details. In the manufacturing process we purely use materials of the highest quality that meet the requirements for product lifetime, security and technical precision.

For example, the housing of our diaphragm gas meters are made of high quality steel or aluminum. The raw material of the essential parts are imported from Europe.

In addition we purely use tested component connections to guarantee that the meters are solid, safe and leakproof. The corrosion resistance is ensured by the use of galvanized steel and die-casting aluminum. In addition to meters are mainly used in residential, commercial and industrial settings.
