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.

The reference plane for the measuring range of the sensors is the
sealing surface of the thread or flange.
Keep in mind that a min. distance must be maintained below the refer-
ence plane and possibly also at the end of the probe - measurement
in these areas is not possible (dead band). These dead bands are
listed in chapter "Technical data". Keep in mind for the adjustment that
the default setting for the measuring range refers to water.
