1. Brief introduction:
G4 residential diaphragm gas meter has high accuracy, high reliability and stable measurement errors, also they have anti-reverse, gas theft features, the products technology has reached the international advanced level, the perfomance indicators are in line withthe requirements ofEN1359 & OlML. Steel housings, elegant in design, high sensitivity and measurement accuracy, stable perfommance, safety and reliability, long-term operation and a wide range of suitable temperament; Designed service life of 12 years.
2. Operating principle:
Four measuring chambers are separated by synthetic diaphragms. The chambers are filled and emptied periodically, and the movement of the diaphragms is transferred via a gear to the crankshaft. This shaft moves the valves, which control the gas fow. The rotations of the gear are transferred via a magnetic or mechanical coupling to the index.
