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.
