Gas Flowmeter Low Pressure

We supply Gas Flowmeter operating at low Gas Pressure. The commercial diaphragm gas meters meet the highest demands with respect to accuracy of measurement and safety. These are supplied in folded form as co-axial and two-pipe versions. Two measuring units with four measuring chambers each are linked together. The stroke of the diaphragms is pneumatically stopped and therefore ensures both low bearing loads and a quiet operation. The synthetic diaphragm is dimensionally stable and stadium shaped. Although the design of the low pressure Gas Flowmeter is very robust, the gas meters are still measuring instruments and as such should be handled with care.

Operating principle :
Four measuring chambers are separated by synthetic diaphragms. The chambers are filled and emptied periodically, and the movement of the Diaphragms is transferred via a gear to the crankshaft. This shaft moves the valves, which control the gas flow. The rotations of the gear are transferred via a magnetic coupling to the index. The temperature compensation facility of the BK-G25T ensures via a bimetallic element that the stroke of the diaphragms is adapted to the current gas temperature.
