The mechanical diaphragm gas meter measures through a mechanical roller, which adds one count for each unit of gas used. The mechanical diaphragm gas meter has the advantages of reliable measurement and stable quality, but the disadvantage is that it is inconvenient to read the meter, and the gas company needs to invest a lot of manpower and financial resources.

[0003] In the use of the existing diaphragm gas meter, the detection mechanism inside the diaphragm gas meter can detect the flow of gas, but when the gas flow is overloaded, it cannot be cut off in time, causing the pipe to fall off and causing gas leakage. UTILITY MODEL CONTENTS
