Sanchuan’s smart prepaid water meter uses IC-card and STS technology for easy top-up, tariff stages, low-balance alerts, and auto shut-off. Ideal for self-service billing, it prevents overuse, fights tampering, and supports long-term data retention with minimal maintenance.
Consumers purchase credit in advance, which is loaded via IC/STS card onto the meter. The meter deducts consumption from the balance in real time and automatically shuts off water when credits run out. Low-balance warnings prompt recharge, and utilities can remotely monitor usage and battery status.

Prepaid water meters help users manage budgets by controlling usage upfront, promote conservation, and minimize arrears for utilities. However, they can cause service interruptions, may restrict essential use, and sometimes malfunction, reducing reliability.
Prepaid meter requires upfront credit and typically has one-way data flow; service stops when credit runs out.
Smart meter (AMI-enabled) records consumption, supports two-way communication, remote readings, leak detection, interval data, and flexible tariffs.
Once credit depletes, the meter automatically shuts off or limits flow. You must top up via IC/STS card or voucher to restore service. Some meters include emergency credit to cover low-balance scenarios.
