Contact-type IC card gas meters feature prepaid and tiered pricing functions, with optional gas leak alarm and valve shut-off capabilities. Users pay gas fees 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 microprocessor 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 supply. Users must repurchase gas and swipe the card to reopen the valve for gas supply. This gas meter can set multiple tier boundaries and various tiered gas prices, automatically determining the appropriate gas price deduction based on the monthly consumption.
1. Ultra-low power consumption technology: Powered by 4 AA dry batteries.
2. Motorized valve technology: Utilizes motorized valve technology for reliable operation and minimal pressure loss.
3. Fully sealed design: All circuits are sealed with high-performance potting compound, with no external electrodes. The excellent sealing ensures stable long-term operation of the circuit board in humid and oily environments.
4. Overcurrent detection technology: Automatically detects and closes the valve when gas flow in the pipeline exceeds the limit.
5. Multi-tier expansion function: Charges based on amount, with monthly gas consumption subject to tiered pricing. Multi-tier expansion can be implemented according to user requirements.
6. Supports one-card meter replacement, maintaining the original tiered pricing after meter replacement.
7. Temperature compensation (optional).
