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nd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sucientto
reach the recommended installation position.
Inthecaseofangeversions,theforkisalignedwiththeangeholes.
When used in adhesive and viscous products, the tuning fork should
protrude into the vessel to avoid buildup. For that reason, sockets
forangesandmountingbossesshouldbeavoidedwhenmounting
horizontally.
IfSITRANSLVL200Eismountedinthellingstream,unwantedfalse
measurement signals can be generated. For this reason, mount
SITRANS LVL200E at a position in the vessel where no disturbances,
e.g.fromlling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ow,mountthesensorsothatthe
surfaces are parallel to the product movement.
