Integrating Flow Velocity, Flow Rate, and Water Level Monitoring to Provide New Solutions for Smart Water Management and Urban Drainage
I. Industry Pain Points: Limitations and Challenges of Traditional Flow Monitoring
With the acceleration of urbanization and increasing demands for water resource management, traditional flow monitoring methods face severe challenges:
- Data Fragmentation: Flow velocity, flow rate, and water level require multiple separate sensors, making data integration difficult
- Environmental Constraints: Contact sensors are susceptible to water quality, sediment, and debris, requiring frequent maintenance
- Insufficient Accuracy: Measurement errors increase significantly during extreme conditions such as storms and floods
- Complex Installation: Requires construction of measuring wells, supports, and other civil engineering facilities, resulting in high costs
During a 2023 urban flooding incident in a southern Chinese city, traditional sensors became clogged with debris, leading to missing monitoring data and delayed drainage scheduling, causing significant economic losses.
II. Technological Breakthrough: Innovative Design of Radar Three-in-One Flow Sensor
Addressing industry pain points, a domestic technology enterprise has successfully developed a new generation radar three-in-one flow sensor, achieving an industry revolution through four core technologies:
- Multi-Parameter Integrated Monitoring
- Uses 24GHz millimeter-wave radar technology to simultaneously measure flow velocity, flow rate, and water level
- Measurement Accuracy: Flow velocity ±0.01m/s, water level ±1mm, flow rate ±3%
- Sampling frequency of 100Hz, capturing real-time dynamic changes in water flow
- Intelligent Signal Processing
- Built-in AI algorithm chip automatically identifies and filters interference from rainfall and floating debris
- Adaptive filtering technology maintains measurement stability under complex flow conditions such as turbulence and vortices
- Supports data quality self-diagnosis, with automatic marking and alerts for abnormal data
- All-Terrain Adaptation Capability
- Non-contact measurement with adjustable installation height from 0.5 to 15 meters
- Wide range design: Flow velocity 0.02-20m/s, water level 0-15 meters
- IP68 protection rating, operating temperature -40℃ to +70℃
- Smart IoT Platform
- Built-in 5G/BeiDou dual-mode communication for real-time data upload to cloud platforms
- Edge computing capability for local data preprocessing and analysis
- Supports seamless integration with drainage scheduling systems and flood warning platforms
III. Application Practice: Success Case in a Smart Water Management Project
In a smart water management project in a provincial capital city, 86 radar three-in-one flow sensors were deployed, achieving remarkable results:
Municipal Drainage Monitoring
