A metallurgical container has a refractory lining for containing a molten metal. A plurality of combination electrodes are provided at various positions of the refractory lining. Each combination electrode includes a refractory body having the property of high electrical conductivity at normal temperatures of the molten metal, and at least one electrical conductor embedded within the refractory body. Refractory material having a low electrical conductivity is positioned between the combination electrodes. A power source is connected to the electrical conductors of the plurality of combination electrodes to achieve first electrical resistances through the refractory bodies from the interior of the metallurgical container to the electrical conductors and second electrical resistances between the electrical conductors. Values of the first and second resistances are measured as parameters indicative of at least one of the level of the molten metal within the container, the temperature of the molten metal and the extent of wear of the refractory lining.
