KROHNE OPTISWITCH 3200C 2wire EN - Manual (Page 13)

The vibrating element should protrude into the vessel to avoid
buildup. For that reason, avoid using mounting bosses for
flanges and screwed fittings. This applies particularly to use
with adhesive products.
If OPTISWITCH 3200 C is mounted in the filling stream,
unwanted switching signals may be generated. Mount OPTI-
SWITCH 3200 C at a location in the vessel where no disturbing
influence from e.g. filling openings, agitators etc. can occur.
Fig. 5: Inflowing medium
To minimise flow resistance caused by the tuning fork,
OPTISWITCH 3200 C should be mounted in such a way that
the surfaces of the blades are parallel to the product
movement.
