Measuring principle
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.
