The industrial meters series E-G10, E-G16 and E-G25 sets a new standard in natural gas metering, specially developed to comply with Italian Regulator Authority Standard 155/2008 it represents a perfect match between traditional diaphragm mechanical meter and advanced electronic high performance metering.

The primary measuring elements consist of two measuring chambers that are separated by synthetic diaphragms; the chambers are filled and emptied periodically by the differential pressure between inlet and outlet. The movement of the diaphragms is transferred via a gear to the crankshaft. This shaft moves the valves, which control the gas flow. The rotations of the gear are then converted into an electrical signal using a custom encoder fitted on the sliding valves. An absolute pressure transmitter is installed outside the carbon steel meter case inside a plastic enclosure to guarantee full access for maintenance, inspection and calibration, if required. The internal meter pressure is then measured and transmitted to the electronic card.
