G4 2Bar Gas Commercial Meter




GME G4 2Bar Meter


The diaphragm meter works on the positive displacement principle wherein the volume received in the inlet side is discharged to the outlet side. Thus making the measurement fully reliable. Further, the diaphragm gas meter works on the differential pressure between inlet and outlet to impulse the diaphragms in the diaphragm boxes. When the gas enters into the meter, it first fills the space inside the inlet meter housing from the rotary valve mouth.



Due to the differential pressure, the gas will alternately enter into the different outlet chamber, alternate charge and discharge will continue till the gas is consumed. The movement of the rotary valve is transferred to the driving gear via the transmission mechanism and accumulates, the gas volume through the meter to index counter by the ratio calibration gears to realize the metrology of the gas meter.


With designing of independent measuring unit structure and high-quality die-cast aluminum-alloy case, the product has accuracy and reliability measurement under high operating pressure. Designing and producing meticulously, test strictly for GA serials gas meter which suitable for NG, LPG, Town gas, marsh gas measuring.

Features:

  • Upper case and the lower case made by high-quality die-cast aluminum-alloy.
  • Surface spray-paint protects from corrosion.
  • Use a high-quality bakelite rotary valve.
  • A diaphragm made by advance gluing and vulcanization processes.
  • The aluminum case can be recycled, environmental-friendly.
  • Broad metrological performance: G4A.
  • High accuracy, long service life with reliability.
  • Lower noise.
  • Equipped with REED impulse generators optional.
