ITRON G4-G6-G10-G16-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 noncorrosive gases. ITRON diaphragm meters are approved for fiscal use.
