Radar Liquid Level Sensor
Radar Level Measurement
76–81GHz millimeter wave radar sensor for precise level measurement of water or slurries in tanks, sumps and reservoirs
Working in the 76-81 GHz range with FMCW (Frequency Modulated Continuous Wave) technology, these radar sensors provide precise water-level monitoring for storage tanks, fire-protection reservoirs, rivers, and open channels. They collect measurements automatically and send the data to the monitoring system without needing anyone on site. Users can access the software and mobile app to check the current water level, review previous readings, save the data they need, and receive alerts if anything changes unexpectedly.

- The radar liquid level sensors work with an 80 GHz FMCW signal and a narrow 6° beam, which helps them stay stable even in the tight and complex conditions found in underground city pipelines and inspection chambers.
- Use an adaptive algorithm designed for natural water environments, so the signal can pass through floating plants and keep tracking the surface level even when there are waves or turbulence.
- High-frequency millimeter-wave technology helps the sensors maintain stable, accurate readings over long periods. They also meet the Level-1 accuracy standard from the Ministry of Water Resources, confirming reliable performance even when conditions change.
- Certified with the Level-1 accuracy standard from the Ministry of Water Resources. They also support RS-485 (Modbus), TTL, and 4G outputs, making it easy to integrate them into a wide range of IoT monitoring platforms without extra complications.
