Features of IC Card Water Meter

1. One table, one card function: Insert a newly issued user card into a new table, and the table will automatically recognize and save the unique code in the card. The code will be automatically recognized when the card is inserted next time, that is, the table will automatically match with the card to prevent Illegal card use.

2. Large-screen LCD often displays: water volume data, valve status, and battery status are clear at a glance.

3. Low voltage detection: When the battery voltage is lower than 3.8V, it will close the motor valve and display "undervoltage" and "close valve". New batteries need to be installed before it can be used again.

4. Insufficient water reminder: When the remaining water in the meter is less than 2.0m3, the valve will be automatically closed and the user will be prompted to buy water. After inserting the card, the valve will be opened and the remaining water can be used until it reaches 0, then the valve will be closed.

5. Anti-counterfeiting function: When the card is inserted backwards or a non-system card is inserted, "card error" will be displayed.
