SITRANS LVL200S l RELAY (DPDT)
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 SITRANS LVL200S is mounted in the filling stream,
unwanted false measurement signals can be generated. For
this reason, mount SITRANS LVL200S at a position in the
vessel where no disturbances, e.g. from filling openings,
agitators, etc., can occur.
To minimise flow resistance caused by the tuning fork,
SITRANS LVL200S should be mounted in such a way that the
surfaces of the blades are parallel to the product movement.
