FIELD: measuring equipment.
SUBSTANCE: present invention relates to methods for electromagnetic measurement of a vertical filling level of a bath with electrically conductive material contained in a metallurgical vessel. Disclosed measuring system comprises: transmitting conductor (5) for generating an electromagnetic field when connected to an alternating power source, receiving conductor (6), which is arranged to sense electromagnetic field for generation of an output signal as a function of vertical filling level, wherein transmitting and receiving conductors (5, 6) are arranged inside metal casing (2), to co-extend with mutual spacing (d) to define spacing area (7) that faces containment volume (3) and extends along periphery of containment volume (3), in a substantially closed circuit, wherein spacing distance (d) is selected so that changes in output signal are influenced by change of electromagnetic field caused by local changes in amount of conducting material, adjacent to said spacing area (7), wherein part of spacing area (7) defines a vertical measurement region, in which spacing area (7) is slanted along periphery of containment volume (3) so as to diverge from horizontal and vertical directions of vessel (1).
EFFECT: purpose of invention is to install a sensor for measuring level, independent of shape of metallurgical vessel, as well as to provide a sensor for measuring level, aimed at increasing signal resolution in vertical direction and improving signal quality.
