Align the sensor in liquids as vertical as possible to the product surface
to achieve optimum measurement.

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 e.g. ladders, limit switches, heating
spirals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring site that the radar sensor
has 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.

If there are agitators in the vessel, a false signal memory should be
carried out with the agitators in motion. This ensures that the interfering
reflections from the agitators are saved with the blades in different
positions.
