The G4 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
