Gas Meter

Operating Manual of G2.5

The G2.5 diaphragm meter is completely acquired by the standard of OIML R31:1995. Its high quality such as wide range of flow rate, high sensitivity, stable performance, good-looking appearance, high safety and long using periods makes it widely used in metrology region of gas, natural gas and liquid petroleum gas etc.

Main structure feature:

1. Wide range of flow rate, high sensitivity and stable accuracy
2. High intensity shell and anticorrosive coating
3. New technique producing diaphragm makes accrual metrology performance possible
4. Magnet kinematical transmission keep excellent sealing
5. Screw tightening of upper case and lower case makes maintenance simple and convenient
6. Electrostatic-plastics-powder-painting of upper and lower case form pure excellent appearance of meters with high burnish and anticorrosive ability

Main specific parameters:

Notification:

• Please make gas piping system cleaning and seal before install the meter.
• Please verify the right connection direction, which is connector at the end of upper case arrow should be connected to gas supply pipe.
• Please install meter upward.
• The tighten torque put on screw connector should be less than    110 N·m,and the bending moment should be less than 40 N·m.
• A valve should be installed before inlet of meter in gas piping system.

  Installation Dimensions

  Using:

• Please make sure the inlet gas pressure is less than the maximum working pressure.
• Don’t use fire to check meter’s leakage.
