Fiscal Metering

Fiscal turbine meters can be recognised by the 3D body lenght. This is one of the requirements for MID approved gas flow meters. Non Fiscal meters are mostly used in the industry as process RMG delivers these meters with a mechanical display or with a digital display. Meters with a digital display can also be equipped with a temperature and pressure sensors for output of vulome corrected flow.
