Function
1. The function of closing the valve in arrears: when the user runs out of water, the background software system can issue a valve closing command to cut off the water source and remind the user to purchase water. (requires background software support)
2. Overdraft function: When the water meter is instructed to close the valve by the background system, press the button once on the water meter to open the water meter valve and continue to use water for three days. After three days, the valve will be permanently closed. , the background software system issues a valve opening command to make the water meter valve open.
3. Protection function: When the water meter encounters magnetic interference, the water meter will automatically close the valve; at the same time, the water meter will record the interference information.
4. Battery under-voltage prompt function: When the battery power is low, the valve does not close the valve, the water can continue to be used, and the "low power" fault will be reported simultaneously, and the user will be reminded to contact the management department to replace the battery; after the new battery is replaced, the "low power" fault will be reported. will be cleared automatically.
5. Power-off valve function: When the water meter is powered off, the valve will not close the valve by default (optional: set the power-off valve function); after re-inserting the battery, the valve will return to the state before the power failure.
6. The display mode of mechanical measurement is not changed, which is convenient for users to check the water consumption intuitively.
7. Without wiring, direct communication can automatically upload data to the server, and the measurement is accurate.
