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.

1 Marking
In case of horizontal mounting in adhesive and viscous media, the
surfaces of the tuning fork should be vertical in order to reduce build-
up on the tuning fork. The position of the tuning fork is indicated by a
marking on the hexagon of VEGASWING 51. 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.
In adhesive and viscous media, the surfaces of the tuning fork should
protrude into the vessel to avoid buildup. Therefore nozzles for flanges
and mountings bosses should not exceed a certain length.

If VEGASWING 51 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
VEGASWING 51 at a position in the vessel where no disturbances,
e.g. from filling openings, agitators, etc., can occur.
To make sure the tuning fork of VEGASWING 51 generates as little
resistance as possible to product flow, mount the sensor so that the
surfaces are parallel to the product movement.
