Introduction and instructions for prepaid water meter
The collection and management of water fees in my country's water supply industry are mostly still based on traditional mechanical water meters. The traditional mechanical water meter adopts the management mode of "water first, pay later", manual meter reading, and manual door-to-door charging. It is difficult to charge, which increases the workload of meter readers for door-to-door meter reading. There is a possibility that users will not pay for water. The water fee recovery rate has been slow to increase.
Introduction of prepaid water meter
The intelligence of the prepaid water meter is based on the IC card as the working medium. The information in the card is read through the radio frequency card reader in the meter. After the CPU microprocessor determines that it is correct, the pre-purchased water in the card is read into the memory in the meter. Then control the switch valve, and finally complete the automatic water supply or stop water.
How to use the prepaid water meter
Users need to apply for an IC card at the business office of the water supply department and purchase the required amount of water. After the water supply department fills the user card with the corresponding amount of water through the prepaid management system, the user only needs to insert the card into the smart water meter at home, and the pre-purchased water amount in the card is automatically read into the meter, and then water can be used normally.
When the remaining amount of purchased water is lower than the set limit, the user needs to take the card to the water supply department business point for recharge business. At this time, the user can also feed back information such as the water status and battery status at home to the water supply management department through the radio frequency card to provide information for the monitoring and macro management of water supply management.
