Diaphragm Gas Meter Is The Representative Of "Household Gas Meter"

Diaphragm gas meter is a type of flowmeter that uses the reciprocating motion of a flexible diaphragm (membrane) to separate gas into fixed-volume "measuring chambers", and accumulates the number of cycles through a mechanical linkage mechanism to measure the cumulative volume of gas.

Product Features

with moderate accuracy: Within the rated flow range, the accuracy can reach ±1.5% to ±2%, fully meeting the requirements for civil trade settlement, and it has good long-term stability.
Extremely low starting flow: It can respond to and measure even the tiniest air flow (such as a small flame), solving the problem of large variations in gas consumption for civil stoves.
Wide measurement range: It can reach 160:1 or higher, suitable for full-range use from the smallest flame to the largest flame.
Pure mechanical structure, no external power supply required, safe and reliable, with a long service life (generally over 10 years).
Internal automatic lubrication: The diaphragm movement drives the lubricator to lubricate the connecting rod mechanism, reducing maintenance needs.
Strong overload capacity: Short-term use beyond the flow rate will not cause damage.

Typical application scenarios

Civil residential gas metering: In thousands of households' kitchens, connected to stoves, water heaters, and heating boilers.
Commercial and public utilities: Restaurants, canteens, schools, and small boiler rooms.
Industrial auxiliary metering: Gas consumption metering in some workshops and dormitory buildings within factories.

Diaphragm gas meters are the cornerstone of "people's metrology" and a paragon of "mechanical ingenuity". Through an exquisitely designed "diaphragm-crank-valve cover" purely mechanical linkage system, they transform invisible gas into visible and reliable figures.
