JWrada®-20 Radar Sensor is designed for short-range level measurement applications that require compact size, reliable performance, and cost-effective operation. It is especially suitable for hydrology, water management, and general liquid monitoring. It can also be used for selected short-range bulk solid applications under simple operating conditions. Because it uses non-contact radar technology, the sensor helps reduce equipment wear and routine maintenance during long-term operation.
This model uses 80 GHz FMCW radar technology and provides a measuring range of up to 10 meters. It features a narrow 13° beam angle and measurement accuracy of up to ±1 mm, enabling stable target detection in compact tanks, open channels, and installations with limited space. Its G¾ threaded connection allows straightforward installation in rivers, lakes, pumping stations, wastewater tanks, and other utility systems.
Smart Communication and Stable Signal Performance
The JWrada®-20 Radar Sensor supports 4–20 mA/HART and RS485/Modbus communication options. It also integrates a Bluetooth 5.0 module, allowing users to perform wireless commissioning, parameter configuration, and operating-status monitoring through the “JW Tools” mobile application.
With cloud connectivity, the device supports remote commissioning, remote monitoring, and firmware upgrades. These functions help operators reduce on-site maintenance work, improve troubleshooting efficiency, and simplify the management of instruments installed across multiple locations.
In addition, the JWrada®-20 Radar Sensor uses Jiwei’s independently developed intelligent echo-learning and adaptive algorithms. It can recognize false echoes, separate multiple echoes, and dynamically track the actual target signal. The sensor automatically adapts to water-surface fluctuations, installation interference, and changing operating conditions. As a result, it maintains stable and accurate measurement output over time.
Compact Design for Easy Field Installation
The device features a compact structure with a G¾ threaded process connection and locking nut. Its small footprint makes it suitable for space-limited installations and enables direct threaded mounting without complicated installation accessories.
The integrated housing and antenna lens are made from lightweight nylon plastic with excellent weather resistance. With an IP66/IP68 protection rating, the instrument is suitable for outdoor monitoring sites and demanding water-management environments.
Its compact design, low maintenance requirements, and economical operation make the JWrada®-20 Radar Sensor an effective upgrade from traditional ultrasonic level meters. It is particularly suitable for projects that require dependable non-contact measurement without a large instrument footprint or complex commissioning procedures.
Typical Applications
JWrada®-20 Radar Sensor is widely used for river and open-channel water-level monitoring, wastewater and sewage treatment, reservoir and sluice-gate monitoring, pumping stations, and urban drainage and flood-warning systems.
It is especially useful in hydrology and water-management projects that require stable, accurate, and easy-to-operate level measurement. The sensor can also be applied to general liquid tanks and selected short-range bulk solid measurement applications under simple process conditions.
