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 amount into the IC card. After the user inputs the information from the IC card into the gas meter, the meter automatically opens the valve to supply gas. During usage, the microcomputer in the gas meter automatically deducts the remaining amount. Once the purchased gas is exhausted, the meter automatically closes the valve to cut off the gas supply. The user must repurchase gas and swipe the card to reopen the valve for gas supply. This gas meter can set multiple breakpoints and various tiered gas prices, automatically determining the appropriate gas price deduction amount based on the monthly usage.
1. Non-contact IC Card (RFID) Technology: Utilizes RFID technology with wireless data transmission, solving issues related to waterproofing, moisture resistance, oil smoke resistance, and anti-tampering.
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 and oily environments.
5. Overcurrent Detection Technology: Automatically detects and closes the valve when gas flow in the pipeline exceeds the load.
6. Multi-Tier Expansion Function: Billing based on amount, with monthly gas consumption using tiered pricing, allowing for multi-tier expansion based on user needs.
7. Supports One-Card Meter Replacement: Maintains the original tiered pricing after meter replacement.
8. Temperature Compensation (Optional).
