MESSKO® MMK
Magnetic oil level indicators for transformers
The MESSKO® MMK magnetic oil level indicator shows the fill level, without needing a float located in the container. The magnetic level gauge can be easily attached to existing flange connections (retrofit) in accordance with DIN 42552. A measuring tube is flanged to the container as a replicate container. Inside, there is a cylindrical float with installed permanent magnet. The indicator rail with the magnetic flaps is on the outside of the measuring tube. Depending on the fill level, the float magnet ensures that the magnetic flaps in the indicator rail turn 180°.
