One meter multi card hot water meter (water control machine)

◆ Usage method
FS multi card hot water meter is mainly used for public hot water equipment in schools. Students who need hot water must deposit their money in the IC in advance at the school management department. When students need to use hot water, they swipe their card on the hot water meter, and the water meter will open the valve to supply water. During the user's use, the smart water meter will deduct the balance in the IC card according to the amount of water used by the student. After use, the water meter will automatically close the valve, realizing that when everyone uses public hot water, they will deduct as much money as they use, and those who use more will pay more, while those who use less will pay less. Avoiding conflicts among classmates over paying water bills. The school implements microcomputer management, which allows for querying, statistical analysis of consumption data, fee collection, and printing of receipts.
