Do not hold SITRANS LVL100 on the tuning fork.
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
data" 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 can damage internal parts of the housing.
Use the hexagon above the thread for screwing in.

Mounting instructions
For threaded versions of SITRANS LVL100 in combination with a
mounting boss with O-ring in front and welding marking.
SITRANS LVL100 with thread sizes ½", ¾" and 1" have a defined
thread. This means that every SITRANS LVL100 is in the same posi-
tion after being screwed in. Remove therefore the supplied flat seal
from the thread of SITRANS LVL100. This flat seal is not required
when using a welded socket with front-flush seal.
Before welding, unscrew SITRANS LVL100 and remove the rubber
ring from the welded socket.
The welded socket is provided with a marking (notch). With 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.

Marking
In case of horizontal mounting in adhesive and viscous media, 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 SITRANS LVL100. 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.
