Diaphragm Domestic Gas Meters G2.5 G4 High Safety ISO9001 certificate
Product introduction
IC (Diaphragm) Gas Meter:The diaphragm gas meter is used as the measurement base
meter, and a new type of smart gas meter composed of a flow signal acquisition module,
an IC card module, a valve control module, and a power management module is added.
In addition to the volume metering functions of coal gas, natural gas, and LPG, the meter
also has functions such as prepayment, electromechanical conversion of metering data,
and valve control.
