1 Marking
In case of horizontal mounting in adhesive and viscous products,
the surfaces of the tuning fork should be vertical in order to reduce
buildup on the tuning fork. On the screwed version you will find a
marking on the hexagon. 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. half a turn. This is sufficient to
reach the recommended installation position.
With flange versions, the fork is directed to the flange holes.
When used in adhesive and viscous products, the tuning fork should
protrude into the vessel to avoid buildup. For that reason, sockets
for flanges and mounting bosses should be avoided when mounting
horizontally.
If VEGASWING 63 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount VE-
GASWING 63 at a position in the vessel where no disturbances, e.g.
from filling openings, agitators, etc., can occur.
This applies particularly to instrument types with long extension tube.

To minimise flow resistance caused by the tuning fork, VEGASWING
63 should be mounted in such a way that the surfaces of the blades
are parallel to the product movement.
Due to agitators, vibrations or similar, the level switch can be sub-
jected to strong lateral forces. For this reason, do not use an overly
