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 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.
4.2 Mounting instructions
For welded socket with O-ring in front and welding marking.
SITRANS LVL100 has a defined thread outlet. This means that
every SITRANS LVL100 is in the same position 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 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.
