Technical parameters of contactless IC intelligent water meter:
Structural form: direct reading water meter;
Nominal path: 15/20/25 (mm);
Working temperature: 0.1-30 (?)

Nominal pressure: 1.6 (MPa).
Function of contactless IC intelligent water meter:
Contactless IC card cold water meter is used to measure the flow of cold water in pipeline, and has the function of automatic charging.
The user will pay the water fee to the management department. The management department will write the amount of water purchased into the IC card. After the user inputs the information from the IC card into the water meter, the water meter will automatically open the valve for water supply. In the process of water consumption, the micro-computer in the water meter will automatically check and reduce the remaining amount. After the water purchased is exhausted, the water meter will automatically close the valve and shut off the water. After the user needs to re-purchase the water. Only then can the valve be opened again for water supply.
