ACD G10 and G16 Diaphragm Meters – High Accuracy Commercial MetersItron Diaphragm ACD G10-G16 meters combine accuracy and long life in a very compact casing. Through our proven know-how in gas measurement, combined with the use of modern engineering and production techniques, Itron has developed this smaller size, highly accurate meter, ensuring reduced shipping costs, and easier handling and simplified installation. Our range of ACD G10-G16 meters are designed for commercial use for gas suppliers and gas utilities worldwide.
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 non-corrosive gases. The ACD 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 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.
