NB-IoT Smart Water Meters: Solution for Modern Water Management

Sanchuan Wisdom began to explore the collection and platform management of residential water use data based on NB-IoT technology in 2015. In 2017, Sanchuan passed the testing and certification of an overseas third-party testing agency and deployed in the Australian market. At the same year, Yingtan's 100,000 NB-IoT smart water meters were put into commercial use.

During our 2022 smart water initiative in Zhejiang Province, Sanchuan Wisdom's NB-IoT meters helped reduce DMA (District Metered Area) leakage by 37% through:

• Real-time pressure monitoring

• Minimum night flow analysis

• Automated leak alerts

  
  

Technology Comparison

Communication Protocols

Sanchuan Wisdom's NB-IoT meters comply with China's CJ/T 188-2018 standard for electronic water meters, featuring:

• IP68 waterproof rating

• EN 1434-2015 metering accuracy

• Built-in anti-tamper sensors

  
  

Key Implementation Data

"Our Fujian project achieved 99.3% daily data completeness using China Telecom's NB-IoT network, surpassing the MIIT's Type A certification requirements." — Sanchuan Wisdom 2022 Annual Technical Report

Three Phase Deployment Strategy:

1. Pilot Phase: 5,000 meter sample size (3-month duration)

2. Validation Phase: Network optimization based on signal strength mapping

3. Mass Deployment: Batch programming using our proprietary configurator tool
