If SITRANS LVL100 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
SITRANS LVL100 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 SITRANS LVL100 generates as little
resistance as possible to product flow, mount the sensor so that the
surfaces are parallel to the product movement.
