The non-contact IC card gas meter features prepayment and tiered gas pricing functions, with the option to add gas leak alarm and valve shut-off capabilities. Users pay the gas fee to the management department, which writes the purchased gas volume 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 volume. Once the purchased gas volume is exhausted, the gas meter automatically closes 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 and deduction amount 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, grease resistance, and tamper protection.
2. Ultra-Low Power Consumption Technology: Powered by four AA batteries.
3. Motorized Valve Technology: Employs motorized 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 greasy environments.
5. Overcurrent Detection Technology: Automatically detects and closes the valve when gas flow in the pipeline exceeds the load 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: Maintains the original tiered pricing after meter replacement.
8. Temperature Compensation (Optional).
