NIVELCO NIVOSWITCH R-400 Series User Manual

Thank you for choosing a NIVELCO instrument!
1. APPLICATION
The NIVOSWITCH R–400 vibrating fork level switches are used for level or flow switching tasks of normal
and explosive liquids. Overfill and dry run protection, as well as pump control, are also possible with the
NIVOSWITCH vibrating fork level switches in low/high fail-safe operating mode.
