The non-contact IC card gas meter features prepaid and tiered gas pricing functions, and can be optionally equipped with a gas leak alarm and valve shut-off function. Users pay the gas fee to the management department, which writes the purchased gas volume into the IC card. After users input the information from the IC card into the gas meter, the gas meter will automatically open the valve to supply gas. During usage, the microcomputer in the gas meter automatically deducts the remaining gas volume. Once the purchased gas volume is exhausted, the gas meter will automatically close the valve to cut off the gas supply. Users must repurchase gas and swipe the card to reopen the valve for gas supply. This gas meter can set multiple tier thresholds and various tiered gas prices, automatically determining the appropriate gas price deduction based on the monthly usage.
1. Non-contact IC Card (RFID) Technology: Utilizes RFID technology for wireless data transmission, addressing challenges such as waterproofing, moisture resistance, oil smoke resistance, and tamper resistance.
2. Ultra-Low Power Consumption Technology: Powered by 4 AA dry batteries.
3. Motor Valve Technology: Employs motor valve technology for reliable operation and minimal pressure loss.
4. Fully Sealed Design: All circuits are sealed with high-performance potting compound, with no external electrodes, ensuring excellent sealing and long-term stable operation of the circuit board in humid or oily environments.
5. Overcurrent Detection Technology: Automatically detects and closes the valve when gas flow in the pipeline exceeds the limit.
6. Multi-Tier Expansion Function: Billing is based on amount, with monthly gas consumption using tiered pricing. Multi-tier expansion can be implemented according to user needs.
7. Supports One-Card Meter Replacement: After meter replacement, the original tiered pricing is retained.
8. Temperature Compensation (Optional).
