Prepaid Steel Shell Smart Gas Meter

1.Measure flow of natural or coal gas 2.Automatically close valve 3.Wireless data transmission 4.Electric machine valve 5.CE

Characteristics

1. Prepaid, RF card technology, wireless data transmission, to solve the problem of waterproof , moisture-proof and anti-attack.

2.Micropower consumption technology: adopt timing test technology, the usual power consumption of gas meter is less than 20μA, such technique can prolong service life of the batteries.

3. Electric machine valve: adopt modern electric machine valve, which work reliably and pressure loss is low.

4. Totally sealed design: all the circuits are sealed by high performance casting glue, so there is no exposed electrode, good leak tightness

5. Anti-attack of external electricity and magnetism: If the gas meter is attacked by external electricity and magnetism, it will automatically close valve and give indication.

6. Micro-computer and microstorage technique: high integrated and high reliability.
