Magnetic Level Controllers MNR 7

The Reed contacts (up to 4) inside the stem, are actuated directly by the magnet float. Wet parts (stem and float) to choose between: or PVC & PP, or PP, or PVDF.

Quick commissioning: 

  • Distance of each contact from sealing surface is fixed (requested on P.O.): No adjustment requested on site to guarantee the exact positioning of contacts.
  • The PP float passes through the BSP 2'' fitting without dismantling the MNR.
  • At the stem bottom a nut limits the float movement: By unscrewing it, the float may be removed. Note: It is recommended to provide the optional flange ND100 to allow the PVDF float to pass through the fitting.


The use of a relay ES2001 will protect the Reed contact and increase its switching power and lifetime.
