STS water meters find applications across various sectors and industries:

 

Residential: In residential settings, STS meters provide homeowners with accurate insights into their water usage, promoting water conservation practices and facilitating budget management through precise billing.

Commercial: In commercial establishments, such as office buildings, hotels, or shopping centers, STS meters offer reliable monitoring of water consumption, aiding in cost allocation, leak detection, and compliance with water usage regulations.

Industrial: Within industrial facilities, STS meters play a crucial role in monitoring water usage for manufacturing processes, cooling systems, and wastewater management. The accurate measurement provided by these meters helps optimize production efficiency and minimize operational costs.

Municipal: In municipal water supply systems, STS meters enable authorities to monitor water distribution networks effectively. By detecting leaks, identifying areas of high consumption, and managing demand, these meters contribute to sustainable water resource management and infrastructure planning.

In conclusion, STS water meters represent a significant advancement in water metering technology, offering accuracy, efficiency, and reliability across various applications.

Their integration into smart metering networks holds promise for optimizing water management practices and promoting sustainability in the face of evolving environmental challenges.

1. Infrared communication: Equipped with an infrared transceiver unit, use an infrared serial port tool to read and write the meter.

2. Handheld communication: The dedicated watch mobile phone software cooperates with the LoRa antenna module to read and write the watch.

3. STS CIU communication:

3.1. The remote control sends short code instructions to read and write the meter.

3.2. Send the token code and receive the return information.

4. LoRa concentrator communication: issue token codes to the meters through the server, and perform read and write data operations on the designated meters.

 

 

1. Valve status indication: displays the open and closed status of the valve.

2. Battery power indication: Use percentage to indicate battery power.

3. Communication indication: When the water meter is in communication status, it indicates that it is connected.

4. Anti-tamper indication: The icon lights up when the anti-tamper alarm is triggered.

6. Magnetic attack indication: The icon lights up when a magnetic attack alarm is triggered.

7. Low balance indication: When the water consumption is greater than the set balance, the icon lights up.

8. There are corresponding fault code indications when input errors, magnetic attacks, tampering, and low voltage alarms occur.

9. The liquid crystal displays the current status of the water meter in real time (communicating, connecting status, waiting status, and constant display status)

10. Constantly displayed status: display of table serial number, remaining water volume, last recharge volume, total purchase volume, and accumulated volume.

11. When entering the token code, such as water meter reception or rejection, secret key expiration, input timeout, used, overflow, etc., all display in compliance with STS531-4, STS531-5-0, STS531-6-1-07 certification document pair display content requirements.

12. Able to read and display water meter frequency, network ID, KEN (key expiration number), KT (key type), EA (decryption algorithm), T1 (rate number), version number, date, and time.

 

 

 

1. Non-magnetic/magnetoresistive metering, use commands to switch.

2. The number of steps that can be set is no less than 10.

3. Through communication tools, the meter can be initialized (reset the water meter), and the meter serial number, meter base, working frequency, network ID, recharge water volume, step water volume, overdraft amount, alarm information, hoarding amount, and holidays can be water use, flow information, valves
