When the gas flows through, different pressures are produced in the four gas chambers of the gas meter, which makes the diaphragm in reciprocating motion. Through a series of drive mechanisms, the metered volume value is transmitted to the counter. The gas consumption is displayed via the counter, so as to achieve the gas metering function.
1) Anti-reverse gear and anti-reverse device can effectively prevent reverse ventilation.
2) Clear and bright mechanical counter display.
3) Precision measurement and stable performance.
