Application
IC card prepaid water meter is the new measuring instrument employing the microprocessor to realize water collection, processing, display and reserving. It is a kind of smart water meter. Compared with traditional way, it can control user's overspend by prepaying for an IC card.
Features
1. IC card water meter use pre-paid way to achieve the new management mode of "Purchase first, then use ".
2. Show the different level price of the water. one card can be used to several meters.
3, Double reading display: mechanical and electronic reading.
4. The unique battery protection.
5. Low power consumption. long life time.
6. Prevent outside magnetic interference
7. Modern appearance.
8.Valve will shut down for warning when the remaining water is less than the warning limitation, and the valve will open up when inserting the card; Valve will termly shut down and open up automatically to prevent rust.
9. The system saves a lot of manpower, and accelerates cash flow, helps to control the non-recoverable charges and do away with the due payment.
