Temperature Compensation Device of Membrane Gas Meter

摘要

The present invention relates to a temperature compensating device for the Max gas meter, the conventional film type gas meter has a characteristic that the intake gas shrinks or expands sensitively to temperature change, but the cam adjusting plate is fixed and installed with the push rod. In the present invention, there is a problem in that the amount of change in the gas cannot be accurately measured due to the contraction or expansion of the gas, and the amount of gas in circulation cannot be accurately measured. One side of the bimetal that reacts to the fixed side is fixed to the contact point of the push rod reciprocating from side to side by the pumping of the diaphragm, and the other end side is fixed to one side of the cam adjusting plate to the cam adjusting plate according to the temperature of the gas to be sucked. By changing the contact position of the push rod, according to the state of the gas to be sucked It is effective to accurately measure the amount of gas actually distributed.
