Functional features

1. Recharge: No value to close the valve, automatic control, no need to read the meter and charge.

2. Strong security: a table (or a household) a card, automatic generation and identification of IC card password.

3. Antimagnetic attack: by magnetic interference, the valve automatically closed, after the card automatically open the valve.

4. Warning and overdraft function: when the remaining water is 0, the valve will be prompted to close, at this time the card can open the valve, allowing overdraft 3 cubic meters. Warning value can be set according to user requirements.

5. Accumulation function: after purchasing the water card again, the remaining water will be automatically accumulated; Accumulated water consumption is automatically and continuously accumulated.

6. Power off memory function: when power off, the remaining water, accumulated water consumption automatic storage.

7. Transfer function: when necessary, can use the transfer card to remove the remaining water, transfer to other tables or input back to the original table.

8. Micro power consumption: the display is normally closed, static working current is less than 16 microampere.

9. Long service life: can repeat reading and writing more than 100,000 times.

10. Anti-clogging function: every 10 cubic water consumption, the ball valve switch once, to prevent cold water long-term action and scaling blocking.

11. Using 6V lithium battery, built-in.

12. One card design: can realize water meter, electricity meter, gas meter, heat meter and other meters of one card management.

13. According to the different needs of customers, provide logical encryption card, RADIO frequency card, CPU card different series of products.

14. Network design, can realize the multi-point recharge management.

15. Radio frequency card table can achieve M1 card ( campus card) compatibility.
