LEVEL SWITCH 8110 • - contactless electronic switch
The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for screwing in.

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 runout. 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.

1 Marking
In case of horizontal mounting in adhesive and viscous products,
the surfaces of the tuning fork should be vertical in order to reduce
buildup on the tuning fork. The position of the tuning fork is indicated
by a marking on the hexagon of LEVEL SWITCH 8110. With this,
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
approx. half a turn. This is sufficient to reach the recommended instal-
lation position.
In adhesive and viscous products, the surfaces of the tuning fork
should protrude into the vessel to avoid buildup. Therefore sockets for
flanges and mountings bosses should not exceed a certain length.
