Product Description

Product Description

NGS series diaphragm gas meter is designed to measure accurately volumes of natural gas, LPG and all non-corrosive gases.

The case of NGS series gas meter is made through die-casting by using the high-quality steel. The measuring unit is injected by using the import engineering plastic. The rotating valve with 360 degree rotation has smaller friction coefficient and better stability, more strength anti-adhesive of impurity in gas, higher sensitivity which design ensured the products quality. The valve and bottom are made of advanced Phenol-formaldehyde synthetic resin with stronger abrasion resistance.

The diaphragm is made of top quality material has been tested 3 million bending test and its service life more than 20 Years. The unique design makes smaller pressure loss, and the performance is better than the international standard mentioned as 200Pa.
