This domestic diaphragm gas meters G4 is gas volume measurement instrument for coal gas, natural gas, LPG etc. It is designed and developed according to world advanced technology, based on our rich experience, with the merits of small size, light in weight, accurate measurement, high sensibility, low noise.



This type gas meter is certified by Chinese standards GB/T6968-1997 and Internation Standard of OIML R137.





Features:



1. Applicable to flexible flow range, highly sensitive, accurate and reliable



2. Independent movements made of high-grade engineering plastics guarantee the precision and resistance.



3. Diaphragms made of new technology are durable and to adapt to a wide temperature range with a more reliable measurement.



4. Bonnet, Block made of Bakelite supplemented stress-resistance management has a good stability.



5. The movement and counter isolation (connected by magnetic drive) ensures the sealing reliability.



6. The hulled table is painted inside and outside, which is anti-corrosion.



The top and bottom tables are sealed with anti-aging rubber with stainless seal rings to ensure reliability and easy maintenance.
