The process fitting must be sealed if there is gauge or low pressure
in the vessel. Before use, check if the sealing material is resistant
against the measured product and the process temperature.
The max. permissible pressure is specified in chapter " Technical

Mounting instructions

For threaded versions of LEVEL SWITCH 8110 in combination with a
mounting boss with O-ring in front and welding marking.
LEVEL SWITCH 8110 with thread sizes ¾" and 1" have a defined
thread. This means that every LEVEL SWITCH 8110 is in the same
position after being screwed in. Remove therefore the supplied flat
seal from the thread of LEVEL SWITCH 8110. This flat seal is not
required when using a welded socket with front-flush seal.
Before welding, unscrew LEVEL SWITCH 8110 and remove the rub-
ber ring from the welded socket.
The welded socket is provided with a marking (notch). For horizontal
mounting, weld the socket with the notch facing upward or downward;
in pipelines (DN 25 to DN 50) aligned with the direction of flow.

you can check the position of the tuning fork when screwing it in.
When the hexagon touches the seal, the thread can still be turned by
