Zenner Atmos Wide-range Diaphragm Gas Meters – EN1359

The Zenner Atmos Wide-range Diaphragm Gas Meters are engineered for versatility and longevity in demanding metering applications. Characterized by precise measurements and constant measuring stability, these meters offer a robust solution for utility providers requiring high reliability across broad flow rates.

Description

In gas metering, the challenge is often maintaining accuracy across varying flow conditions while resisting environmental wear. The Zenner Atmos Wide-range Diaphragm Gas Meters address these challenges with advanced mechanical engineering. The gas meter is suitable for various gas media, providing flexibility for different infrastructure requirements.

The core technical advantage lies in the internal mechanism. An integrated calibration system coordinates the movement of the valves in relation to the optimum gas flow. This precise synchronization guarantees the excellent linearity of the error curve, ensuring that the meter remains accurate even at low flow rates. This is critical for capturing consumption data during off-peak usage or pilot light operation.

Furthermore, the design focuses on minimizing maintenance. Due to the optimum sliding characteristics of the valves, the Qmin value remains stable throughout the meter’s service life. This unique valve dynamic also makes the gas meter resistant to contamination, preventing particulate buildup that causes drift in lesser instruments. The high measuring range enables precise metering results across the entire operational spectrum.

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.
