Locally store historical data including water level, rainfall, supply voltage and alarm records;
Auto-trigger alarms for threshold violations, and wirelessly transmit data to the management platform via 2G/3G/4G/LoRa;
Support remote parameter configuration, firmware upgrade, device time calibration and historical data polling;
Link with cameras and environmental sensors to capture on-site images and environmental readings.
The radar water level gauge is a high-frequency millimeter-wave non-contact water level measuring instrument with a maximum measuring range of up to 70 meters. Adopting the Frequency Modulated Continuous Wave (FMCW) radar ranging principle, it delivers accurate water level measurement. It supports storage and transmission of measured data such as water level and empty height, and an optional integrated RTU module provides data collection, local storage and 2G/3G/4G wireless transmission functions, compatible with rainfall and environmental sensors.
The whole machine features IP68 ingress protection and wide operating temperature ranging from -35℃ to 75℃, with sleep current lower than 1.3mA. It supports local debugging via Bluetooth and remote firmware upgrade, and automatically sends water condition alarms. The device reduces on-site manual inspection to realize unattended remote hydrological monitoring, and is widely applied to water level monitoring for rivers, reservoirs, irrigation channels and other facilities in existing water conservancy and hydrological projects.
✅️ Operates at 24GHz frequency with a measuring range up to 70 meters.
✅️ Adopts non-contact planar measurement; free from abrasion and contamination.
✅️ Features narrow beam angle and concentrated energy to boost echo intensity, effectively avoiding interfering objects.
✅️ Resists water corrosion, foam, water vapor, as well as interferences caused by temperature and pressure fluctuations and other atmospheric changes.
✅️ Delivers high signal-to-noise ratio (SNR) to suppress wave fluctuation interference.

The radar beam angle is 11°, and the minimum channel bottom width A ≈ 0.193H. Narrow channels will cause measurement errors due to beam interference from channel walls. The device shall be installed in the center of the channel with the antenna parallel to the water surface.
The self-report mode is recommended for solar-powered low-power stations, which only connects to the network during data reporting. The compatible online mode supports real-time platform polling at any time with permanent network connection, yet with higher power consumption.
