Innovative Millimeter Wave Radar Technology Solves Flow Monitoring Challenges in Complex Working Conditions
I. Industry Pain Points: Limitations of Traditional Flow Measurement
In fields such as hydrological monitoring, urban drainage, and water conservancy engineering, flow measurement has long faced numerous challenges:
- Contact measurement limitations: Traditional mechanical flow meters are susceptible to water quality, sediment, and debris
- Complex installation and maintenance: Requires construction of measuring wells, supports, and other civil engineering facilities
- Failure in extreme weather: Measurement accuracy significantly decreases during storms, floods, and other extreme conditions
- Delayed data transmission: Difficulty in achieving real-time remote data transmission and early warning
