Residential Diaphragm Gas Meter

G1.6-Residential Diaphragm Gas Meter

U-ideal residential diaphragm gas meters (G1.6/ G2.5/ G4) feature in gas volume measurement for natural gas, coal gas, LPG and all non-corrosive gases. It is designed and developed as per world advanced technology, based on our extensive experience, with the advantages of small size, light in weight, high sensibility, accurate measurement and low noise.

Product features

☆wide range of flow-rate, high accuracy and long-term stability.

☆compacted size and light weight.

☆Die-casting steel cases of the measure unit adopting galvanization technology ensures its good anti-corrosive ability.

☆Magnetic transfer between measuring unit and counter ensures the smooth operation of the meter and prevent gas leakage.

☆Plastic-coating of meter cases provide nice appearance and good anti-corrosive ability.

☆Screw tightening of upper and lower parts of cases ensures easy maintenance and convenient disassembling.
