The process fitting must be sealed if there is gauge or low
pressure in the vessel. Before use, check if the seal material is
resistant against the measured product and the process
temperature.
The max. permissible pressure is stated in chapter "Technical
data" in the "Supplement" or on the type label of the sensor.
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 on the housing can damage its
rotational mechanical parts.
To screw in, use the hexagon above the thread.

4.2 Mounting instructions

For welded socket with O-ring in front and welding marking.
LEVEL SWITCH 8110 has a defined thread runout point. 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 O-ring.
Before welding, unscrew LEVEL SWITCH 8110 and remove
the rubber ring from the welded socket.
The welded socket has a marking (notch). For horizontal
mounting, weld the socket with the notch facing upward or
downward; in pipelines aligned with the direction of flow.
