Under what circumstances will the prepaid IC card smart water meter automatically close the valve?
The situations of the automatic valve closing of the ic card water meter mainly include:
1. Battery undervoltage: If the battery inside the IC card smart water meter is out of power (insufficient power), the battery cannot provide normal support for the actuator or the circuit part inside the water meter. In this case, the valve will The charging current is carried out to close the valve.
2. Insufficient water volume: if the remaining water volume inside the water meter is lower than the set warning value, the valve of the ic card water meter will automatically close the valve and alarm once. The smart water meter will automatically close the valve and alarm. In this case, the user needs to go to the corresponding location to recharge the water bill.
3. Strong magnetic attack: If the smart ic card water meter is attacked by strong magnetic, the anti-magnetic ring inside the water meter will be induced, and the inside will send out a signal accordingly to the reed switch and the actuator to the valve part, which will make the valve Shut off the valve. In this way, for some users who want to use strong magnetism to steal water, not only will the situation of water stealing and water leakage be avoided, but also the valve of the water meter will be closed, and the tap water cannot be used normally.
