ZENNER Gas Meters Diaphgram

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 im- ported 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.
