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.
In the case of flange versions, the fork is aligned with 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 the instrument is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount the
instrument 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 make sure the tuning fork of SITRANS LVL200E generates as little
resistance as possible to product flow, mount the sensor so that the
surfaces are parallel to the product movement.
