Zenner Two-pipe Diaphragm Gas Meter – G1.6 & G2.5

The Zenner Two-pipe Diaphragm Gas Meter sets a high standard for accuracy and durability in residential and light commercial metering. Available in sizes G1.6 and G2.5, this meter is specifically engineered to provide constant measuring stability and high reliability over an extended service life.

Description

In the precise world of gas measurement, mechanical stability is the key to long-term accuracy. The Zenner Two-pipe Diaphragm Gas Meter addresses this requirement through advanced internal engineering. The device features an integrated calibration system that perfectly coordinates the movement of the valves in relation to the optimum gas flow. This mechanical synchronization guarantees excellent linearity of the error curve, ensuring that measurements remain accurate even at low flow rates where other meters might drift.

A standout feature of this design is the optimum rotating characteristics of the valves. This specific dynamic ensures that the Qmin (minimum flow) value remains stable throughout the meter’s operational life. Furthermore, this valve design makes the gas meter highly resistant to contamination, preventing the accumulation of particulates that can compromise performance.

Designed for seamless integration, the two-pipe configuration allows for standard installation into existing gas networks. With its robust construction and focus on metrological precision, this meter is suitable for various gas media, providing a versatile solution for utility providers and facility managers.

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.
