NIVELCO NIVOSWITCH R-400 User Manual

Thank you for choosing a NIVELCO instrument.
We are convinced that you will be satisfied with our product!
1. APPLICATION
A NIVOSWITCH R–400 type vibration forks are applicable for level switching or flow switching tasks of
normal and explosive liquids. Overfill or dry run protection, as well as pump control, is also possible with the
NIVOSWITCH vibration forks in low/high fail-safe operation mode.
