The sensor emits a continuous radar signal through the antenna. The emitted signal is reflected by the medium and received as an echo by the antenna.

The frequency difference between the emitted and received signal
is proportional to the distance and depends on the filling height. The determined filling height is converted into a respective output signal and output as measured value.
