Customizable intelligent water meter with powerful functions

1. The customizable smart water meter module supports the minimum consumption function by cycle, settling based on water usage. When the monthly usage is below the set minimum consumption limit, the difference between the monthly usage and the set minimum consumption limit can be automatically deducted during settlement; When the monthly usage is greater than or equal to the minimum consumption limit, no additional deduction will be made. The minimum consumption function can only be activated after opening an account and is consistent with the cycle of the ladder. It can be enabled or disabled through user card water purchases or rate setting cards. When deducting the minimum consumption based on quantity, the amount of water that needs to be additionally deducted is not included in the cumulative and monthly usage, and the unit price of the deducted water usage is deducted using a 1-step unit price.

2. The tiered water pricing function module uses the amount as the settlement unit and can set settlement cycles of 1 month, 2 months, 1 quarter, 6 months, or 1 year. It can automatically settle according to the set steps and rate table based on the water consumption of each cycle. The module supports 3 steps. Spare 1 set of rate table.

3. Customizable smart water meter measurement and prepayment function

Adopting dual pulse sampling for measuring pulses, the two pulse sampling points are sequentially merged once to form a measuring signal of 0.1 m3. Compatible with reed switches and Hall sampling. According to the measurement signal, decrease the remaining amount in the table until the remaining amount is exhausted, and then close the valve. Simultaneously increase the monthly water consumption in the table and accumulate the water consumption.

After sending the recharge command through the water purchase recharge app, the water meter will add the current recharge amount to the original remaining amount. When the recharge is correct, the indicator light will turn on. When synchronizing the device, the new remaining amount and related information will be fed back and displayed on the app interface.

5. Customizable smart water meter storage function

The water meter is equipped with a maximum storage limit. If the total amount of water purchased exceeds this limit when added to the remaining amount on the meter, a customized smart water meter app will prompt a recharge failure and indicate that the recharge limit has been exceeded; After waiting for the remaining amount in the table to accumulate with the water purchase amount and fall below the set maximum limit, the APP will send the recharge package again to complete the recharge.

6. Query function

The Bluetooth water meter APP can send query commands to return user information and meter related information, and display them in the APP.

7. Remaining amount alarm

When the remaining amount is less than or equal to the valve closing alarm amount, the valve will be closed to prompt the user to recharge. After synchronizing the APP device, the valve can be opened and the user will be prompted to pay in a timely manner.

8. Valve closing and payment

The valve closing alarm amount can be set for the meter. When the remaining amount of the meter is less than or equal to the valve closing alarm amount, the meter will close the valve. At this time, the user can send a Bluetooth command through the "device synchronization" button on the Bluetooth water meter APP interface. The meter can restore water use and prompt the user to recharge and pay.

9. Customizable low voltage protection function for smart water meters

The water meter usually measures the voltage once a day. When the meter detects that the battery voltage has been below 2.87V ± 0.05 for 12 consecutive days [with a certain load test], the valve will automatically close. Open the APP to synchronize the device and continue using the valve. The APP interface prompts the user to contact the management and replace the battery. When the battery voltage is detected to be below 2.60V ± 0.05, the valve should be completely closed, and the user cannot open the valve. The user must notify the management department to replace the battery before continuing to use it.

10. Customizable smart water meter anti magnetic attack function

The water meter provides automatic protection function. When a magnetic field approaches, the valve will automatically close and the APP will prompt "sampling fault". Please check whether there are strong magnetic field objects or water immersion in the surrounding environment of the water meter. After processing, the device can synchronously open the valve. If it cannot be restored, the maintenance personnel can be notified to repair the water meter.

11. During normal use, if the meter valve is closed and the synchronous device displays a fault prompt, please notify the maintenance personnel to repair the water meter as soon as possible.

12. Valve maintenance function: The valve is automatically maintained once every 15 days in a semi closed state.

13. Power on self-test: Power on the meter, and the meter will perform status self-test. It can detect the battery voltage and automatically open or close the valve according to the specific situation of the meter.
