Description
Diaphragm gas meter
One of the important equipment used in measuring the consumed volume of natural gas is the diaphragm gas meter. In order to measure the volume of gas in this type of gas meters , after gas flow passes through half of the left and right chambers , the diaphragm is displaced and the reciprocating movement is transmitted by the flag rod to the arms and then the form of a rotary movement to the crankshaft of the gas meter counter.
The rotary movement of the crankshaft of the gas meter counter is transferred to the mechanical counter by magnetic coupling, and the consumed volume of gas is displayed on the counter.
In accordance with the requirements defined in the standard of National Iranian Gas Company No. IGS-M-IN-101 , Gas Souzan company considers general requirements in order to design and manufacture diaphragm gas meters and measuring accuracy rate and allowable errors of the meter and types of tests and as well as the materials used in the manufacturing of diaphragm gas meters.
Diaphragm gas meters manufactured and designed by Gas Souzan company in all sizes and have the necessary approvals from the technical and industrial research laboratory of National Iranian Gas Company and National Standard Organization.
