Mounting
page 19
For nozzle mounting, the nozzle should be as short as possible and
its end rounded. This reduces false reflections from the nozzle.
The antenna edge should protrude at least 5 mm (0.2 in) out of the
nozzle.

Fig. 14: Recommended socket mounting of NivoRadar 4100
If the reflective properties of the medium are good, you can mount
NivoRadar 4100 on sockets longer than the antenna. The socket
end should be smooth and burr-free, if possible also rounded.
Note:
When mounting on longer nozzles, we recommend carrying out a
false signal suppression (see chapter " Parameter adjust-
ment").
You will find recommended values for socket heights in the following
illustration or the table. The values come from typical applications.
Deviating from the proposed dimensions, also longer sockets are
possible, however the local conditions must be taken into account.

The mounting location of the radar sensor should be a place where
no other equipment or fixtures cross the path of the radar 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 point that the radar
sensor has a " clear view" to the measured product.
