80GHz Radar Level Meter: The Reliable Solution for River and Lake Water Level Measurement
Water level fluctuations in natural bodies of water such as rivers, lakes, and estuaries are crucial for flood control, ecological management, and water resource allocation. Traditional pressure-based and float-level meters are often affected by factors like sediment accumulation, water vapor interference, and temperature variations, leading to unstable data and frequent malfunctions. To address this challenge, Jiwei Technology offers the 80GHz Frequency-Modulated Continuous Wave (FMCW) Radar Level Meter, designed to provide stable, reliable measurements in complex water environments with high-frequency measurement, intelligent algorithms, and a non-contact structure.
High-Frequency Radar Technology for Stable Natural Water Level Measurement
Jiwei’s 80GHz radar level meter utilizes a narrow beam design that minimizes the blind spot, providing accurate measurement of water level changes in rivers, lakes, and channels. Compared to ultrasonic or low-frequency radar devices, this radar level meter is immune to environmental factors like fog, wind, water vapor, and temperature changes, offering superior anti-interference capabilities.
Whether faced with drastic water fluctuations due to storms or steam interference during winter, the device ensures stable operation and continuous, reliable data, making it ideal for water resource management and ecological analysis.
Case Study: Accurate Water Level Monitoring in the West River Tributary
In Zhaoqing, Guangdong Province, Jiwei’s 80GHz radar level meter was deployed at a hydrological station along a tributary of the West River. This area is significantly impacted by upstream reservoir operations and tidal variations, leading to frequent and large water level fluctuations.
“Previously, we used traditional pressure sensors, but after heavy rainfall or high sediment levels, the data was often erroneous. After switching to Jiwei radar level meters, the measurements have been much more stable and the setup was significantly easier,” shared the on-site engineer.
The radar level meter connects via Bluetooth to the “Jiwei Smart Control” app, allowing engineers to configure the device directly from the embankment without needing to enter the river or use scaffolding. This greatly improved installation efficiency and worker safety. Over four months of operation, the device has withstood extreme weather conditions such as typhoons and water evaporation, consistently providing high-quality water level data to support flood control and scheduling systems in the region.
Non-Contact Design Reduces Maintenance Pressure
The Jiwei radar level meter operates on a non-contact measurement principle, eliminating the need for direct contact with the water. This significantly reduces issues like corrosion, scaling, and sediment build-up. It is particularly suited for deployment in humid, high-moisture, or hard-to-reach river and wetland environments, lowering maintenance frequency.
The device’s housing is rated to IP68 for protection, making it suitable for all outdoor climate conditions. It also offers flexible installation options, including threaded, flanged, and hanging mounting, allowing quick adaptation to different site conditions.
Smart Platform for Easier Remote Configuration
With the integrated Bluetooth module and “Jiwei Smart Control” platform, users can configure parameters, query status, and access historical data via their smartphone—no need for a computer or specialized tools. This greatly reduces the complexity of setup and maintenance.
The radar level meter also features intelligent signal processing algorithms with dynamic echo recognition capabilities, ensuring it can accurately lock onto valid echoes even in the presence of intense water surface turbulence or clutter, providing real-time data tracking and stable output.
Versatile Application Across Multiple Industries
From urban river water level monitoring to mountainous reservoir level warnings, and from ecological conservation areas to agricultural irrigation channels, Jiwei radar level meters can be customized to meet specific environmental needs. Its compact structure and standardized interfaces enable deployment in confined or temporary monitoring sites such as bridges, culverts, embankments, and tidal zones.
Moreover, the device is designed to meet the functional safety standards of SIL2/3 and complies with IEC61000 electromagnetic compatibility standards, making it suitable for a wide range of industries, including environmental protection, water resources, petrochemical, and energy. While it is not yet officially SIL certified, it is built to adhere to these stringent standards, offering a reliable, low-maintenance water level monitoring system for users across these sectors.
Conclusion: The Ideal Choice for Smart Water Management
As climate change intensifies and the demand for water resource management increases, traditional water level monitoring technologies are no longer sufficient for modern intelligent water systems. The Jiwei 80GHz radar level meter, with its high precision, strong anti-interference, low maintenance, and smart configuration capabilities, is becoming a key device in the construction of next-generation smart water management systems.
In the future, Jiwei will continue to innovate, improving product performance and user experience to support more efficient and intelligent ecological monitoring and water resource management.
