STS prepaid water meters STS prepaid system consists of prepaid water meters concentrators and the main station system

The STS prepaid water meter mainly describes and presents its functions

Solving the billing problem for water supply companies: The STS prepaid water meter adopts a payment-before-use model. Users need to purchase water in advance and complete the recharge through methods such as entering the recharge code, thus avoiding the difficulty of water supply companies' billing and ensuring the revenue of water supply companies.

Realizing automatic data collection and remote monitoring: Through wireless communication technologies such as LoRa, the STS prepaid water meter can achieve semi-automatic or fully automatic remote reading of data. Water supply companies can either have the meter readers carry data collectors to walk around the installation area to collect data, or deploy concentrators in areas with dense water meter installations to realize the remote automatic and regular upload of water meter data, improving the meter reading efficiency and reducing management costs.

Facilitating multi-channel water purchase for users: Users can obtain recharge codes through various methods, such as purchasing at the local water supply business hall or making online payments. Then, by inputting the 20-digit recharge code through the indoor display unit (CIU), they can achieve prepaid recharge of the water meter. The operation is convenient and fast.

Ensuring the security and accuracy of water management: The STS prepaid water meter follows the STS standard protocol and has features such as unique keys, unique codes, and unique verification, ensuring the security of data transmission. At the same time, the water meter can accurately measure water consumption, providing an accurate basis for water fee settlement, and avoiding disputes caused by inaccurate measurement.

Offering multiple practical functions: The water meter has a balance alarm function. When the remaining water reaches the set alarm value, it will automatically close the valve to remind users to purchase water in time. In addition, it may have holiday water usage settings, overdraft functions, valve control, data storage functions, etc. It can store 10 years of monthly water data, making it convenient for users and water supply companies to query and manage.

Supporting tiered water pricing: Water prices can be set for no less than 10 tiers, in line with the national policies on rational utilization and management of water resources. Through the price lever, it guides users to save water.

Standard Compliance: The STS standard originated in South Africa and is a globally recognized open standard for prepaid systems. The STS prepaid water meter transmits water purchase codes, encryption and decryption, key management, and a series of prepaid management-related instructions according to the STS standard protocol. It has features such as unique keys, unique codes, and unique verification, ensuring the security of the code data.

System Composition: The STS prepaid system consists of prepaid water meters, concentrators, and the main station system. The prepaid water meter is responsible for water consumption measurement, receiving TOKEN codes for recharge, and abnormal detection, etc.; The concentrator connects with the water meter through communication methods such as LoRa, and is responsible for remote communication between the water meter and the main station; The main station can read water meter data through the concentrator, transmit TOKEN code recharge, and transmit alarm information, etc.

Prepaid Function: Users can purchase water through multiple channels and obtain 20 recharge codes. The codes can be input through the indoor display unit (CIU) to complete the recharge process.

Data Reading: Remote reading of meter data can be achieved through LoRa wireless communication. Water companies can assign data collectors and handheld devices to collect data, or deploy concentrators in densely installed meter areas to achieve remote automatic and regular data upload.

Multiple Payment Methods: Supports post-payment, prepaid, and mixed charging methods. Water charges can meet various requirements, and tiered water pricing can be set.

Alarm Function: Features balance alarm, low voltage alarm, and cover opening detection alarm functions. When the balance is insufficient, the battery voltage is too low, or the water meter is illegally opened, the water meter will emit an alarm sound or use other methods to alert users and the management department.

Other Functions: Equipped with automatic valve control, real-time clock, anti-magnetic interference and recording, and customizable overdraft functions. Some water meters also have a power-off data storage function, capable of storing over 5 years of data.

Appearance Design: Adopting integrated and modular designs, it is simple and elegant, has a beautiful appearance, is easy to operate, and has IP68-level waterproof performance, suitable for various harsh and humid environments.

Application Scenarios: Mainly used for detecting and recharging water in residential buildings, enterprises, and institutions. It is an ideal metering and charging instrument for modern management of water fees and management departments, helping water companies solve the problem of difficult charging, improving the efficiency of meter reading, and reducing management costs.
