Contact IC card gas meter with prepayment and ladder gas price function, can be added with leakage alarm valve shut-off function. Users will give the gas bill to the management department, the management department will write the purchased gas quantity into the IC card, users will input the information in the IC card into the gas meter, the gas meter will open the valve for gas supply automatically, in the process of users' use, the microcomputer in the gas meter will automatically reduce the remaining quantity, after the purchased gas quantity is exhausted, the gas meter will close the valve and cut off the gas, and the users need to re-purchase the gas and then brush the card in order to open the valve for gas supply.
The gas meter can set multiple cut-off points and various ladder gas prices, and automatically determines the appropriate gas price reduction amount according to different monthly usage.
Key Technology
- Ultra-low power consumption technology: 4 No.5 dry batteries power supply. Motor Valve Technology:Adopting motor valve technology, reliable work and small pressure loss. Fully sealed design: all lines are sealed with high-performance potting adhesive, no exposed electrode, good sealing to ensure that the circuit board in the humid, sooty environment for a long time stable work.
- It ensures that the circuit board can work stably for a long time in humid and oily environment.
- Overcurrent detection technology: automatically detects and closes the valve when the gas flow in the pipeline is overloaded. Multi-step expansion function: billing according to the amount of monthly gas consumption using step gas prices, according to user needs to achieve multi-step expansion function to support a card to change the meter, after changing the meter still maintain the original step price.
- Temperature compensation (optional)
