Mechanical Diaphragm gas meter

When the flowing gas passes through the gas meter, it is blocked by the friction of the pipe and the mechanism, the internal gas will generate a pressure difference between the inlet and outlet of the gas meter. The Diaphragm gas meter transforms the linear reciprocating motion into a circular motion through the internal mechanical structure, and then drives the mechanical roller counter to rotate through the circular motion; each time the diaphragm reciprocates, a certain amount of gas is discharged, and finally, the roller turns through a counting unit to achieve the roller rotation metering display effect.

Electronic Diaphragm gas meter

The prepaid diaphragm gas meter with the aluminum case is based on a mechanical basis with the addition of electronic metering, usually with magnets on the mechanical roller and at the highest accuracy position, and with two reed tubes on the upper and lower part of the roller.
