Product Description

MESSKO MFLOC 2.0 detects pump failure in power transformer oil or water cooling systems immediately and reliably. A specially designed paddle is placed as flow resistance in the circulating cooling liquid to monitor the flow of the cooling fluid. When the pump is on, the flow pressure applied to the paddle, ensures that it rotates to an end stop and functions safely in case of laminar or non-laminar medium flow.

The new generation is based on the MESSKO MFLOC, a product that has been in the product portfolio since 2010. It was further developed, subjected to functional tests and optimized. This ensures that there are no changes to the predecessor model during assembly and retrofit installations.

The highlights:

  • Quick and easy installation - no paddle regulation or adjustment for different flow velocities required
  • Separate sensor and indicator components with patented magnetic coupling for absolute air tightness
  • Two permanently set switching contacts (changeover)
  • Available for oil and other cooling fluids, and in an additional model for water cooled circulations

The new paddle

   

The MESSKO MFLOC 2.0 has been developed with an improved paddle design. The paddle is made from Polyamide Copolymer, 50% Glass Fiber – a proven material in the Reinhausen Group. The optimized functionality of the new design was confirmed by internal and external lab tests during the stage of development.
