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.
VEGASWING 51 has a defined thread outlet. This means that every
VEGASWING 51 is in the same position after being screwed in.
Remove therefore the supplied flat seal from the thread of
VEGASWING 51. This flat seal is not required when using a welded
socket with front-flush seal.
Before welding, unscrew VEGASWING 51 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 (DN 32 to DN 50) aligned with the direction of flow.
