摘要： The vertical filling level of electrically conductive material in a cavity of a metallurgical vessel is measured by a system including a transmitting conductor for generating an electromagnetic field when connected to an alternating power source, and a receiving conductor which senses the electromagnetic field for generation of an output signal. The conductors are arranged inside a metal casing of the vessel to co-extend with a mutual spacing defining a spacing area that faces the cavity and extends along the periphery in an essentially closed loop. The mutual spacing is selected such that changes in the output signal is dominated by changes to the electromagnetic field caused by local changes in the amount of the conductive material adjacent the spacing. Part of the spacing area defines a vertical measurement region slanted along the periphery so as to diverge from the horizontal and vertical directions of the vessel.
