High-Precision 80GHz Hydrology Radar Level Transmitter (Up to 85m) | FRM5000
An ultra-precise, long-range 80GHz FMCW radar engineered specifically for rivers, canals, flood warning systems, and open-water hydrology.
Utilizing a self-developed CMOS millimeter-wave RF chip with a massive 5GHz sweeping bandwidth, the FRM5000 delivers unmatched sub-millimeter level accuracy (±1 mm) across distances of up to 85 meters. Encased in a rugged IP67 weather-proof housing, this sensor remains entirely unaffected by heavy rain, wind, ambient temperature changes, or rising steam.

Description
The FRM5000 is a professional-grade 80GHz FMCW non-contact radar level sensor designed for hydrological monitoring and environmental defense systems. Whether installed over rapid rivers, deep reservoirs, or municipal sewer networks, the FRM5000 provides continuous, real-time depth data with high accuracy.
Unlike traditional hydrostatic or ultrasonic level gauges, the FRM5000 does not touch the media, requiring zero physical maintenance and removing the risk of sensor damage during extreme flood events.
Where the FRM5000 Excels:
-
River & Hydrology Networks: Monitor seasonal river flow, tides, and canal depth from bridges or overhanging structures.
-
Flood Warning Systems: Reliable outdoor tracking of urban water logging, mountain runoff, and reservoir safety.
-
Water Resource Management: Continuous tracking of water levels in large open-air reservoirs and intake channels.
-
Industrial & Environmental Outfalls: High-accuracy discharge and pollution-monitoring systems.
Advanced 80GHz Technology Advantages:
-
True ±1 mm Accuracy: The advanced 5GHz operating bandwidth allows the radar to resolve tiny changes in water levels, giving engineering-grade accuracy even over long distances.
-
Highly Focused 6° Beam: The narrow beam angle prevents the signal from bouncing off riverbanks, side walls, or installation brackets, ensuring a clean echo returned directly from the water surface.
-
No On-Site Wiring Hassle: Available with integrated mounting brackets and low-power configuration options, making remote solar-powered setups highly efficient.
Features
-
Low Power Operation: Built specifically with remote monitoring stations in mind, the FRM5000 features low-power electronics that extend battery and solar-powered system lifespans up to 3+ years.
-
Weather-Proof IP67 Enclosure: Designed to survive the elements. The rugged IP67 housing keeps the sensitive internal radar RF chip completely safe from heavy rainstorms, snow, and dense outdoor humidity.
-
Compact Lens Design: The integrated, flush lens prevents spiderwebs, condensation, and dirt from gathering on the antenna, further reducing the need for manual maintenance visits.
-
Configurable Smart Alarms: Directly set high and low level alarm thresholds within the device to instantly flag critical overflow risks or drought situations.
