The STS prepayment water meter is a type of smart water meter system that uses a prepayment method to manage users' water consumption.
The water meter can set tiered water pricing (no less than 10 levels) and can store up to 50 TIDs, making it convenient for users to check.
Monthly water usage data can be stored for 10 years. The prepaid water meter features functions such as overdraft, low balance alerts, valve control, and Token code reset for the meter.
The CIU uses LoRa wireless technology to issue Token codes, with a communication distance of no less than 300 meters in residential areas.
The CIU can pair one-to-one with the user's STS water meter, and the pairing can be changed if needed.
The LCD display screen makes it easy for users to read meter data and recharge information.
