In the context of increasingly scarce water resources, how to achieve efficient and convenient water management has become a key issue. The STS prepayment water meter (Standard Transfer Specification) is an intelligent water meter solution designed to address this problem. Through advanced prepayment technology, it helps users achieve accurate metering, convenient payment, and efficient water management.
·Ladder water prices can be set (not less than 10 steps), can store 50 TIDs for easy query
· Monthly water data can be stored and recorded for 10 years, overdraft, insufficient balance alarms, valve control, Token code can reset the water meter, etc. Function;
· CIU uses LoRa wireless to issue Token codes, and the communication distance in residential areas is not less than 300 meters
· CIU and user STS water meters can be paired one-to-one, or the pairing can be changed
· LCD function display facilitates users to read meter data and recharge information
· Independent battery compartment, the battery is easy to replace
· Mechanical and electrical separation design makes after-sales service
