The use of the card water meter is very simple. From the user's point of view, just insert the card into the water meter. The working process of the card water meter is generally as follows: insert the card containing the amount into the card reader in the water meter. After the microcomputer module recognizes and downloads the amount, the valve opens and the user can use water normally. When the user uses water, the water quantity collection device starts to collect the water consumption, and converts it into the required electronic signal, supplies it to the microcomputer module for measurement, and displays it on the display module. When the user's water consumption drops to a certain value, the microcomputer module will sound an alarm, prompting the user to pay with the card to purchase water. If the amount of water used is exceeded, the microcomputer module will automatically close the electronically controlled valve and cut off the water supply. Until the user inserts the paid card and restarts the valve for water supply.
