Caution:
Do not hold VEGASWING 63 on the tuning fork. Particularly with
flange or tube versions, the tuning fork can be damaged just by the
weight of the instrument. Transport coated instruments very carefully
and avoid touching the tuning fork.
Remove the packaging or the protective cover just before installation.
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 Instructions for installation
VEGASWING 63 has a defined thread starting point. This means
that every VEGASWING 63 is in the same fork position after being
screwed in. Remove therefore the supplied seal from the thread of
VEGASWING 63. This seal is not required when using a welded
socket with O-ring in front.
Keep in mind that this welded socket is not suitable for coated instru-
ment versions.
Screw VEGASWING 63 completely into the welded socket. The
later position can be determined already before welding. Mark the
appropriate position of the welded socket. Before welding, unscrew
VEGASWING 63 and remove the rubber ring from the welded socket.
The welded socket has a marking (notch). Weld the socket with the
notch facing upward, or in case of pipelines (DN 32 up to DN 50),
aligned with the direction of flow.
