The 60G Radar Level Transmitter utilizes advanced 60 GHz Pulsed Coherent Radar (PCR) technology to provide reliable, non-contact level monitoring for natural hydrological environments. Compared to traditional methods (ultrasonic, pressure, float), it delivers superior accuracy, real-time response, and broad adaptability without being affected by environmental factors or medium properties. With very low beam energy, it ensures complete safety for people and ecosystems. No on-site calibration is required, making it an ideal choice for long-term, low-maintenance hydrological data collection in rivers, reservoirs, lakes, irrigation channels, and waterways.
60 GHz PCR radar – superior resolution, accuracy, and measurement stability
Maximum range 15 m, minimum blocking distance 0.15 m
Narrow beam angle with focused energy – strong anti-interference, high reliability
Robust performance in harsh outdoor conditions: rain, snow, fog, dust, water mist, varying light
Independent of medium density or dielectric constant – no recalibration required
Extremely low radar emission power – safe for humans, animals, and environment
Bluetooth commissioning via smartphone app – quick setup, configuration, and on-site diagnostics
Flexible output interfaces – supports multiple circuit options for SCADA, telemetry, or controllers
The transmitter operates on Pulsed Coherent Radar (PCR):
It emits short microwave pulses that propagate through air, reflect off the water surface, and return to the sensor. The distance is precisely calculated by measuring the time-of-flight (ToF) between transmission and reception of each pulse. Advanced signal processing ensures stable and accurate readings even under challenging surface conditions.
