Itron gas meter diafragma
The ACD diaphragm meters are used for applications requiring high precision
and large rangeability at low pressure (below 1 bar gauge).
They are supplied in two versions - a compact and a standard version (single and two pipe).
Due to the volumetric principle of the diaphragm meters,
its metrology is not influenced by installation conditions.
They are designed for use with natural gas, manufactured gas and other noncorrosive gases.
The ACD diaphragm meters are approved for fiscal use.
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 two 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.
