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.

The reference plane for the measuring range of the sensors is the
