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xturescrossthepathoftheradarsignals.
Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point 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.

If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
interferingreectionsfromtheagitatorsaresavedwiththebladesin
dierentpositions.
