Non-contact IC card gas meters feature prepaid and tiered gas pricing functions, and can be optionally equipped with gas leakage 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 users input the information from the IC card into the gas meter, the meter automatically opens the valve to supply gas. During usage, the microcontroller in the gas meter automatically deducts the remaining gas volume. Once the purchased gas is exhausted, the 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 breakpoints and various tiered gas prices, automatically determining the appropriate gas price and deducting the corresponding amount based on the monthly usage.
1. Non-contact IC card (RFID card) technology: Utilizes RFID technology for wireless data transmission, addressing challenges such as waterproofing, moisture resistance, oil fume protection, and tamper resistance.
2. Ultra-low power consumption technology: Powered by 4 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 and oily environments.
5. Overcurrent detection technology: Automatically detects and closes the valve when gas flow in the pipeline exceeds the rated capacity.
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 card replacement for meter exchange, maintaining the original tiered pricing after replacement.
8. Temperature compensation (optional).
