Welding work
Inflowing medium
PBD-51041388
Higher sockets or sockets with a bigger diameter can generally be
used. They can, however, increase the upper blocking distance (dead
band). Check if this is relevant for your measurement.
In such cases, always carry out a false signal suppression after instal-
lation. You can find further information under "Setup procedure".
Fig. 6: Mounting socket
When welding the socket, make sure that the socket is flush with the
vessel top.

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.
