4.2 Mounting instructions
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
nearly down to the lowest point of the bottom. Keep in mind that
measurement all the way down to the tip of the probe may not be pos
-
sible. The exact value of the min. distance (lower dead band) is stated
in chapter "
Technical data
".

Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
Do not mount the instruments in or above the filling stream. Make sure
that you detect the product surface, not the inflowing product.
