Description:

The diaphragm temperature compensation gas meter is a common diaphragm gas meter with a temperature compensation mechanism. When the temperature of the gas flowing through the movement changes, the synthetic bimetallic strip with different thermal expansion coefficients on the compensation mechanism is triggered to produce flexural deformation, thereby adjusting the diaphragm stroke and changing the rotation volume, thereby offsetting the volume difference caused by thermal expansion and contraction of the gas and achieving fair measurement. The temperature compensation function enables the diaphragm gas meter to have a wider range of environmental adaptability and improve measurement accuracy.
