Prepaid IC card campus water meter

Prepaid IC card campus water meterFeatures:
1. Prepaid function, pay first, use later; The purchased water amount can be written into the IC card water meter through the user card. When the purchased water amount is used up, that is, when the remaining water amount is zero, the valve will automatically close and cut off the user's water supply; After the user pays for water again and writes the purchased water amount into the IC card water meter through the user card, the valve can be automatically opened to resume water use;
2. Ladder water price, one card with multiple meters;
3. Monitoring function: When the remaining water is used up, the water meter valve automatically closes, and when the battery voltage is insufficient, the water meter valve automatically closes and an alarm is triggered; When a malfunction occurs, record the date when the valve loses control.
4. Dual display function of mechanical and electronic readings;
5. Battery protection function, stable performance, and wide applicability;
6. Ultra low power consumption and long service life.
7. Data retention function: The data in the water meter can be retained for 10 years without losing data in case of power failure.
