TG-G1.6/2.5/4.0 Diaphragm Household Gas Meter

 

Application for TG-G1.6/2.5/4.0 Diaphragm Household Gas Meter

 

 

  TG-G1.6/2.5/4.0 Diaphragm Household Gas Meter are positive diaphragm meters within the meter there are two chambers formed by movable diaphragms. With the gas flow directed by internal valves, the chambers alternately fill and expel gas, producing a near continuous flow through the meter. As the diaphragms expand and contract, levers connected to cranks convert the linear motion of the diaphragms into rotary motion of a crank shaft which serves as the primary flow element.  TG-G1.6/2.5/4.0 Intelligent Directly Read Resident Gas Meter comply with requirement provision in GB/T6968-1997 Diaphragm Type Gas Meter.
