1. Brief introduction:
G6-G40 Commercial gas meters are kind of multi-flow commercial gas meters. They have high accuracy, high reliability and stable measurement errors, also ant-reverse, anti- thelt leatures, the products technology has reached the internatonal advanced level, the performance indicators are in line with the requirements of EN1359 & OlML Steel housings, elegant in design, high sensitivity and measurement accuracy, stable performance, 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 flow.
The rotations of the gear are transferred via a magneticor mechanical coupling to the index.
