Product Description
STS (Standard Transfer Specification) smart water meters adopt a management model of "pay first, then use water". Tokens can be issued to STS water meters through CIUs, infrared units, or meter keyboards to achieve prepaid top-up and valve-switching functions. Meanwhile, remote meter reading and data management can be realized when paired with a concentrator. Its prepaid model, high-precision measurement, and remote management capabilities provide a convenient water usage management solution for water utilities.
Product Features
- The protection level of the STS prepaid water meter reaches IP68.
- S.H.Meters adopts an independent battery compartment design, allowing users to replace the battery conveniently without opening the control box.
- The prepayment water meter supports the setting of 10 different tiered water prices.
- Low-power circuit design enables a battery life of over 6 years.
- The STS Prepaid water meter supports multiple alarm functions, such as low voltage alarm, magnetic interference alarm, cover removal alarm, water meter movement alarm, balance alarm, overdraft alarm, and abnormal flow alarm.
- The smart water meter is equipped with a free water sales management platform that provides comprehensive functions, including water meter recharge, balance alarm, price adjustment, etc., helping the water utility department manage water meter data efficiently and improve the management level.
- The shell is designed with a unique UV-resistant material, which can effectively resist the impacts of high temperature and direct sunlight, thus extending the service life.
- The design of mechanical and electrical separation reduces the after-sales cost and improves the work efficiency of after-sales service.

Products workflow
After the user recharges at a water sales point (service hall, website, or self-service terminal), the sales system communicates with the cloud platform to generate a 20-digit token code. The user then inputs the token code into the prepaid water meter through the CIU. The water meter receives and verifies the token, and upon successful verification, the water volume is credited to the meter account, allowing the user to use water normally.
