ake note for VEGAPULS 62 with rinsing air connection that the holes
in the antenna and in the process fitting correspond. This ensures a
sufficient air flow (the air is led through the holes to the feed system. A
rinsing of the parabolic antenna in total is not intended).

4.4 Mounting instructions
T he illustrations with the following mounting instructions show a
VEGAPULS 62 with horn antenna. The mounting instructions apply
analogously also to the version with parabolic antenna.
W hen mounting the sensor, keep a distance of at least 200 mm
(7.874 in) to the vessel wall. If the sensor is installed in the center of
dished or round vessel tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see chapter
"
Setup").
