ABSTRACT OF THE DISCLOSURE The level in a container of the interface between a first liquid and a second liquid on the surface of the first liquid can be determined by placing a single electrode at a predetermined position within the container, detecting a first voltage potential at the electrode determined by an electro- chemical reaction occurring at the electrode between one of the liquids and the electrode, and thereafter determining the interface between the first liquid and the second liquid by detecting a change to a second voltage potential different from said first potential and determined at the electrode by an electrochemical reaction occurring at the electrode between the other of the liquids and the electrode when the other liquid comes into contact with the electrode; the method has particular applicability in determining the position of the interface between a molten metal and a slag in a ladle from which the amount of molten metal in the vessel may be determined.
