G4 Aluminum-shell diaphragm gas meter

diaphragm gas meter with aluminum case The upper case and lower case of this mechanical gas meter are made of the high quality aluminum-alloy by die-casting production and treated the both surfaces of the meters for the corrosion-resistance treatment with the pure polyester powder plastic coating (for outdoor),which is in conformity with European ROHS environmental protection requirement. The big rotating valve with 360' rotation has the smaller friction coefficient and better stability, more strength anti-adhesive capability of impurity,higher sensitivity.Its service life is more than fifteen(15)years. The gas meter has the features of compact size, beautiful appearance, high sensitivity, accurate measurement, good stability, strong reliability, highpressure resistance, more corrosion resistance in Outdoor, longer service life, and easier maintenance.
