Zenner Atmos HP Diaphragm Gas Meter HPG1.6A, HPG2.5A, HP G4A – EN1359

The Zenner Atmos HP Diaphragm Gas Meter HPG1.6A, HPG2.5A, HP G4A represents a high-grade measuring instrument designed for precision and durability. Combining solid build quality with advanced technical engineering, this meter ensures constant measuring stability and high reliability over a long service life.

Description

In the field of gas metering, long-term accuracy and safety are paramount. The Zenner Atmos HP Diaphragm Gas Meter HPG1.6A, HPG2.5A, HP G4A is engineered to deliver precise measurements even under challenging conditions. The core of its performance lies in its integrated calibration system, which perfectly coordinates the movement of the valves in relation to the optimum gas flow. This sophisticated mechanism guarantees excellent linearity of the error curve, ensuring accurate readings even at very low flow rates.

Durability is a key feature of the Atmos design. The meter utilizes optimum rotating characteristics for its valves, which ensures that the Qmin value remains stable over time. Furthermore, this design makes the gas meter highly resistant to contamination, reducing the risk of blockage or measurement drift.

Safety and compliance are built into every unit. The Atmos® diaphragm gas meter meets the rigorous requirements of the EN1359:2017 and OIML R137-1 (2012) standards. Whether used for natural gas, LPG, or other non-corrosive gases, this device provides the trusted performance that utility providers and engineers demand.

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.
