Domestic Diaphragm Gas Meter:
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.

Extended Functions:
1. Supporting anti-reverse mechanism is available. In the case of reverse connection, the gas meter will stop work, which can prevent users stealing gas. And it can effectively prevent the mistaken connection of the water heater to the outlet of the gas meter, thus to avoid high-pressure water entering the gas meter or the gas pipeline.
2. Supporting anti-inversion structure is available. If the meters were inclined at any angle or inverted installed, the gas meter can automatically adjust to the positive reading, thus to avoid users stealing gas by inclining the meters.
This mechine is used for worker collecting data from end user, the data can be transfered to gas compnay center, which do not need worker input the data to computer anymore.
For the after-sale service, if any damage which is not made by human beings, the repairing / exchanging service will be provided for you. We promise exchanging in 1 year, repairing in 3 years and the lifelong remote guidence .
