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

► Install the flange plate with G¾ process connection (→ Accessories) 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.
