Prepaid IC Card Gas Meter
During the period of gas power supply, the microcomputer inside the gas meter will automatically subtract the gas power, when the purchased power is used up, the gas meter will automatically close valve and stop gas power supply. At this moment, the customer has to purchase gas again to open the valve of gas meter. With support of software and IC card reader-writer, gas administrative department can manage the remaining gas, total used gas, and total purchased gas etc. By this kind of meter can improve management efficiency, no need of house call fee-charge and avoid owing. Intellect IC card gas meter device has unique integral structure, Inner valve and unit counter, high measure precision, high reliability. Multiple encryption has been used in IC card in order to ensure everyone's benefit, management system and meter have been used in order to open an account, buy gas, zero clearing. complement card, transfer rest gas, logout an account
3.Two-way data protection
4.Anti-attack of external magnetism
1. Prepaid RF card technology: using wireless data transmission, 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. Electrical valve: adopt modern electrical valve, which work reliably and pressure loss is low.
4. Totally sealed design: all the circuits are sealed by high performance casting glue, there is no exposed electrode, good leak tightness.
5. Anti-attack of external electricity and magnet: If the gas meter is attacked by external electricity and magnet, it will automatically close valve and give indication.
6. Micro-computer and micro-storage technique: high integrated and high reliability.
