We have three models of this type diaphragm gas meter- G1.6-T, G2.5-T and G4-T, all of the three models can be identified with temperature compensation mechanism. A synthetic bi-metal with different thermal expansion coefficients on the compensation mechanism will be triggered in the condition of the temperature of the gas flow changed. The length of the crank will be changed to adjust the movement of the diaphragm thanks to the bended deformation, thereby the cyclic volume is changed. This structure is designed to counteract volume differences that caused by contraction of gas and thermal expansion. The features mentioned above could improve the diaphragm gas meter's environmental adaptability and the measurement accuracy.
Our Diaphragm Gas Meter with Temperature Compensation can used for measuring various gas media: Natural gas, town gas, liguid gas, biogas, methane gas, etc.
