atmos^®- diaphragm gas meter with temperature compensation

product overview:

two-pipe diaphragm gas meter g1.6-t |g2.5-t | g4-t

the gas meters g1.6-t| g2.5-t| g4-t are equipped with a temperature compensation mechanism.
when the temperature of the gas flow chan-ges a synthetic bi-metal with different thermal expansion coefficients on the compensation mechanism will be triggered.
the deformation is ben-ded so the length of the crank will be changed to adjust the movement of the diaphragm.
thereby the cyclic volume is changed. its special design will counteract the volume differences which caused by the thermal expansion and contraction of gas.
this kind of meter could improve envi-ronmental adaptability of diaphragm gas meter and greatly improve the measurement accuracy.
