ZMETERG4ELSTER
BK-G4 Credit Meter with 1″ BS746 Connections
£65.99
The residential diaphragm gas meter BK-G4 meet the highest demands with respect to accuracy of measurement and safety. It incorporates both innovative features and gas measurement know-how of many decades. The BK-G4 is supplied in folded form as co-axial and two-pipe version.
The stroke of the diaphragms is pneumatically stopped and therefore ensures both low bearing loads and a quiet operation. The synthetic diaphragm is dimensionally stable and stadium shaped.
High-grade materials and components as well as the patented curve K-System ensure a high quality standard. The K-System perfectly coordinates the movement of the valves with the actual gas flow to the measuring chambers. This ensures excellent linearity even with utilizing small valves.
Due to the optimised slides, Qmin of BK-G4 is stable and the gas meter is not susceptible to contamination (RPF 0.65 to BS4161). The measuring unit is adjusted by a patented needle-and-scale system. Although the design of the BK-G4 is very robust, the gas meters are still measuring instruments and as such should be handled with care.
