GAS METER ACTARIS DIAPHRAGM METERS G25 G40

Through decades of knowledge in the field of commercial and industrial diaphragm gas meters, our G25 and G40 meter sizes combine accuracy of measurement and long life in the field.

Application

The G25-G40 diaphragm meters are used for applications requiring high precision and large rangeability at low pressure (below 1 bar gauge).
Due to the volumetric principle of the diaphragm meter, its metrology is not influenced by installation conditions.
They are designed for use with natural gas, manufactured gas and other non-corrosive gases.
The G25-G40 diaphragm meters are approved for fiscal use.

Operating Principle

The movement of the diaphragm is caused by the pressure difference between the inlet and the outlet of the meter. The reciprocal filling is controlled by means of 2 sliding valves.
This oscillating movement is transformed into a rotational one and is mechanically transmitted to the totalizer through a magnetic coupling or a stuffing box.
