Appearance description of IC card water meter

The appearance of the IC card water meter is basically similar to the appearance of a general water meter, and the installation process is basically the same. The use of the IC card water meter is very simple. From the user's point of view, insert the IC card card into the water meter. The working process of the IC card water meter is generally as follows: The IC card containing the amount is inserted into the IC card reader/writer in the water meter. After the computer module recognizes and downloads the amount, the valve is opened, and the user can use water normally. When the user uses water, the water collecting device starts to collect the water consumption, converts it into the required electronic signal and supplies the microcomputer module for measurement, and displays it on the LCD display module. When the amount of water used by the user drops to a certain value, the microcomputer module sounds an alarm, prompting the user to pay for the purchase of water by paying the card. If the amount of water is exceeded, the microcomputer module will automatically close the electronically controlled valve and cut off the water supply. Until the user inserts the paid IC card, it starts to open the valve for water supply again.
