Prepaid smart card purified water meter:

·Prepaid function: Two way transmission of water information through IC card, purchase water first and then use water, automatic valve closing and water stoppage without charge

·One card function: This meter supports multiple meters on one card, and can realize one card for water, electricity, gas, and heating

·Display function: Users can intuitively view various information of the water meter, such as the amount of water purchased this time, remaining water, cumulative water consumption, switch valve status, power shortage reminder, etc., with clear and intuitive display

·Pre alarm function: When the remaining water level reaches the set alarm value, the water meter automatically shuts off to remind users to purchase water in a timely manner. After inserting the card, users can continue to use it until the water level reaches zero and close the valve
