► Arrange for a bore hole in the tank lid� It must have a minimum diameter d to
enable sufficient transfer of the measured signal to the probe (fig� 7-11)� The
diameter (d) depends on the wall thickness of the tank lid:
Wall thickness [mm] 1���5 5���8 8���11
d [mm] 35 45 55
► Install the flange plate with the flat surface showing to the tank and fix it with
appropriate screws�
If necessary, a seal (A in fig� 7-12) can be inserted between flange plate
and tank� Some flange plates are supplied with a seal� If this is not the
case, use a suitable seal�
► Ensure cleanness and evenness of the sealing areas, especially if the tank is
under pressure� Tighten the fixing screws sufficiently�
► Slightly grease the sensor thread with a suitable paste�
► Insert the unit into the process connection�
► Tighten it using a spanner� Tightening torque: 35 Nm
