The STS water meter is an intelligent prepaid water meter that operates on a "pay first, use later" basis. Users can recharge the water meter by entering a 20-digit code.
·Tiered Water Pricing Setup (at least 10 levels), 50 TID Storage:
The water meter supports setting tiered water pricing, helping manage different billing standards based on water usage. Each TID (unique user identification code) can store up to 50 entries, making it easy to query and manage when needed.
·Monthly Water Usage Data Storage for 10 Years:
The water meter stores monthly water usage data for up to 10 years, making it convenient for users or administrators to track long-term water usage patterns. It also features overdraft and low balance alarms, valve control, and Token code reset functionality.
·CIU Uses LoRa Wireless Technology to Issue Token Codes, with a Communication Distance of No Less Than 300 Meters:
The Central Interface Unit (CIU) uses LoRa wireless technology to issue Token codes, with a communication range of at least 300 meters.
·One-to-One Pairing of CIU with Each User's STS (Standard Water Meter):
The CIU pairs one-to-one with each user's STS (standard water meter), ensuring that each user's water usage data is accurately recorded and managed. Users can also change the pairing as needed, offering more flexibility.
·Water Meter Equipped with an LCD Display Screen:
The water meter comes with an LCD display, allowing users to view real-time water usage data and recharge information. The display is clear and intuitive, making it easy for users to understand the current water meter status.
·Independent Battery Compartment for Easy Battery Replacement:
The prepaid water meter features an independent battery compartment, making battery replacement quick and easy. This design ensures that users or service personnel can replace the battery quickly, preventing the water meter from malfunctioning due to battery issues.
·Electromechanical Separation Design:
The water meter adopts an electromechanical separation design, meaning the electronic and mechanical parts can be separately maintained and replaced. This improves repair efficiency and reduces maintenance costs
