Klinger 8701 is a Guided radar for continuous level measurement in tanks / silos with liquid or solids.
A Guided Radar works with electromagnetic waves transmitted along a guide tube / cable, when the wave encounters a change in the dielectric constant, part of the signal will be reflected.
The Klinger 8701 series offers as follows:

Level measurement with Time and Flight principles is reflection or echo measurement based on measuring the duration of a high-frequency pulse emitted by a sensor - The pulse is reflected by the surface and detected again by the sensor.
The elapsed time is a measure of the distance traveled in the empty part of the tank. By now subtracting this value from the total tank height, the level height is obtained which, via an amplifier, is converted into a contact signal or an analog output signal.
