Zenner Atmos Diaphragm Gas Meter G1.6S, G2.5S, G4S

Description

In the precise world of gas metering, stability over time is the most critical factor. The Zenner Atmos Diaphragm Gas Meter G1.6S, G2.5S, G4S achieves this through advanced mechanical design. The core of its performance lies in an integrated calibration system that perfectly coordinates the movement of the valves in relation to the optimum gas flow. This synchronization guarantees excellent linearity of the error curve, ensuring that billing data remains accurate even when gas consumption drops to minimal levels.

A key technical advantage of this series is the optimum sliding characteristics of the valves. This design feature ensures that the Qmin value remains stable throughout the meter’s lifecycle. Furthermore, these sliding characteristics make the gas meter highly resistant to contamination, preventing the buildup of particulates that typically degrade measurement quality in lesser devices.

The high measuring range enables precise metering for flow rates from 0.016 m³/h to 6 m³/h, accommodating a wide variety of load profiles. Fully compliant with EN1359:1998/A1:2006 and OIML R137-1 (2012) standards, the Atmos meter provides the safety and regulatory assurance required for modern gas distribution networks.

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.
