Most people's understanding of prepaid water meters is to pay first and then use water. But in fact, the prepaid water meter has many other functions. Let's take a look together.
Main features of prepaid water meter
1. Pre-payment function: Two-way transmission of water use information through IC card. First purchase water and then use water, automatically shut off the valve and stop water without charge.
2. All-in-one card function: The meter supports all-in-one card function for hydropower.
3. Display function: the user can visually view the information of the water meter. Such as the current purchase of water, remaining water, accumulated water consumption, switch valve status, power shortage reminder, etc. The display is clear and intuitive.
4. Pre-alarm function: When the remaining water volume reaches the set alarm value, the water meter will automatically close the valve. To remind the user to buy water in time, the user can continue to use it after swiping the card until the water volume reaches zero and close the valve.
5. Valve closing function: When the remaining water volume is zero, the water meter automatically closes the valve. Only the user can open the valve after purchasing water and swiping the card.
6. Low voltage alarm function: when the battery power is insufficient or the battery is replaced. The water meter automatically closes the valve, and can increase the power-off valve shut-off function,
7. Hoarding limit function: When the recharge amount exceeds the limit, the water meter will not read the water purchase amount in the card. It cannot be read until the sum of the remaining water quantity in the water meter and the current purchase water quantity is less than the limit.
8. Anti-attack function: When the water meter is attacked by external strong magnetism or strong electricity, the water meter will automatically close the valve. The valve can only be opened after the external interference is removed, and the attack information is automatically recorded.
