Fig. 10: Recommended threaded socket mounting of VEGAPULS C 11
If the reflective properties of the medium are good, you can mount
VEGAPULS C 11 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 adjustment
").
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 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 signal suppression
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.
