In liquids, direct the sensor as perpendicular as possible to the prod-
uct surface to achieve optimum measurement results.

The mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the microwave signals.
Vessel installations such as for example, ladders, limit switches, heat-
ing spirals, struts etc. can cause false echoes that interfere with the
useful echo. Make sure when planning your measuring site that the
radar signals have a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage should be
carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
