Functional characteristics of prepaid IC card water meter

1. Prepaid function: Users purchase water first and then use it, and the valve will be closed and water will be stopped if the fee is not paid.

2. One-card function: one card realizes the control of electricity meter and water meter.

3. Synchronous display function: LCD screen and base meter display water consumption synchronously. Even if the circuit fails and the LCD cannot display, it can also refer to the mechanical display.

4. Prompt and alarm function: battery undervoltage, insufficient water available, strong magnetic interference and other fault information will be prompted and alarmed on the LCD.

5. Data upload function: Every time a user purchases water, the relevant information will be brought back to the management system, so that the management can understand the user's water consumption and the status of the meter.

6. Valve self-maintenance function: the valve rotates at regular intervals, and the valve scale is removed in time to ensure the flexibility of the valve.

7. Anti-hoarding water function: The lower limit of recharge can be flexibly set through the software to prevent users from hoarding water.

8. Anti-drip function: cooperate with the anti-drip base meter to realize the anti-drip function.

9. Blacklist query: Users who do not come to buy water for a long time can be blacklisted to monitor the water consumption of users.

10. Easy to replace the battery: there is a cover specially designed to replace the battery on the bottom of the water meter. It is very convenient to replace the battery. Batch replacement of the battery is no longer a problem for the water management department.

11. "Water soaking" function: The product adopts the overall sealing and waterproof process in the process, so it can work in a humid environment or in the case of short-term soaking in water.
