ABSTRACT:
A device for determining the position of an interface between different fluids in a tank or container is provided. This device has a plurality of cells, placed one below another and mounted on a structure which is placed in the tank or container, each cell consisting of three electrically conductive elements, isolated from each other, the first element of each cell being adapted to be connected to an AC signal source, the third element of each cell being adapted to be connected to zero potential, and the second element of each cell being adapted to be connected to a receiver for detecting the transmitted AC signal.
