The intelligent prepaid RF IC card water meter is equipped with an electronic module on the basis of a mature and reliable mechanical water meter, and also stores water usage data. Its data transmission and transaction settlement are carried out through RF cards, realizing the transformation of users paying at the business office.

Manufacturer of smart intelligent prepaid water meter

The intelligent prepaid water meter is a mature and reliable mechanical water meter based on GB/T778.1-2018 “Measurement of Water Flow in Closed Pipelines – Drinking Cold Water Meter” CJ/T133-2012 “LC Card Cold Water Meter”. It is equipped with an electronic module, which can measure and display water consumption, automatically control water consumption according to the agreement, and automatically complete the calculation of water fees for tiered water prices.

Intelligent prepaid water meter features

1. Using low-power technology, typically with a low power consumption of 0.5uA, greatly extends the battery’s lifespan.
2. Electric ball valve technology can achieve low pressure loss and low power consumption.
3. The valve should automatically switch on and off once regularly to prevent rusting and scaling.
4. Fully sealed design: Both the circuit and motherboard are sealed, allowing for long-term use in humid environments or water.
5. Anti magnetic attack technology: If an external magnetic attack is received, the valve will automatically close until the attack alarm is manually cleared.
   Implement functions
6. Adopting non-contact RF card technology, data transmission and transaction settlement are carried out through RF cards.
7. Implement the payment before use method to prevent water bill arrears.
8. It can record and display water consumption electronically, and automatically control water consumption according to agreements, completing the calculation of tiered water prices automatically.
9. Users can display water usage information such as “remaining” and “cumulative” by swiping their user card, and when recharging, they can display “water purchase information”
   At the same time, display the on/off status of the valve.
10. The RF card water meter is equipped with a storage limit, which is set when the sum of the purchased water volume in the user’s card and the remaining water volume in the meter exceeds the storage limit. The water meter does not accept user card recharge operations.
11. When the remaining water level in the meter reaches the alarm water level, the valve will automatically close to remind the user that there is not much remaining water in the meter. At this time, the user will swipe the meter and the valve will open for emergency use.
