IC Card Remote Prepaid Water Meter
The water-purchase and recharge function is a common feature. First, insert the recharge card into the prepaid water meter, and then insert this card into the user’s already recharged card to start using the service.
1. A prepaid water meter is a type of meter that has a set limit on the amount of water that can be stored. When a user performs an operation on the card, if the total remaining water in the meter—after accounting for the amount already used—exceeds the preset storage limit, the meter will refuse further top-ups to the user’s card. This measure serves as a safeguard for the assets stored on the user’s card.
2. Implement measures to prevent water theft and protect consumers’ rights and interests. 
3. There’s also a feature called “valve closure for payment.” This feature ensures that when paying the bill, the large-caliber prepaid water meter accurately measures the water usage without any error. The valve of the prepaid water meter will only open to supply water once the remaining water balance after recharging exceeds the amount of water already overdrafted from the prepaid balance.
