Abstract

1. Apparatus for measuring the level of molten metal (M) in a vessel, especially a continous casting mould (K), by sensing the secondary electromagnetic fields emanating from the liquid metal, the apparatus comprising a primary coil (P, P2 , P4 ) creating a time varying electromagnetic field, two secondary measurement coils (S, S2 , S'2 ; S4 , S'4 ) extending along substantially the entire height of the primary coil and positioned on the opposed sides of the primary coil and means for delivering the difference of the signals sensed by the secondary measurement coils, characterized in that at least one of the coils (P; P2 ; P4 ; S, S'; S2 , S'2 ; S4 , S'4 ) is subdivided into at least two superimposed stages (40, 41, 42, 43, 44) having different magnetic properties and in that at least on stage of the secondary measurement coils (S, S2 , S4 ) includes at its ends connections for relaying the calibrating signals.
