NIVELCO NIVOFLIP MAK-200 User manual

Thank you for choosing a NIVELCO instrument!
1. APPLICATION
NIVOFLIP MAK–200 type magnetic level switches are used for NIVOFLIP magnetic-lamella bypass level
indicator as an optional level switch.
OPERATING PRINCIPLE:
Mounted on suitable connection flanges on the side of the tank, the liquid level in the bypass tube and the
tank is equal. A magnetic float tracks the liquid's level in the stainless-steel bypass tube. A permanent magnet
is incorporated in the float, which operates the MAK–200 adjustable bistable reed switch through the stainless-
steel side of the tube and provides a non-contact signal to the microswitch.
The position of the switch can be changed to adjust the switching level. The distance between the two MAK–
200 units must be at least 60 mm (2.4″).
The cable is led through a cable gland. The maximum cross-section of the wire is 0.75 mm2(AWG18). The
level switch is attached with a hose clamp.

Default start-up
Ensure that the switches are set to the correct position for the float position before starting up. If necessary, move
the float vertically up and down once by the switches before installing the float. It will set the switching positions to
the float's default (bottom).
