4.4 Mounting instructions
The illustrations with the following mounting instructions show a
LEVEL TRANSMITTER 8137 with horn antenna. The mounting
instructions apply analogously also to the version with parabolic
antenna.
When 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").
If you cannot keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo
storage later with existing buildup.
