ABSTRACT:
A liquid rheostat includes a conductive element which surrounds multiple electrodes. The element provides a multiplicity of current paths between the electrodes at a given depth of electrolyte solution thus decreasing current concentration of the electrodes. In order to further decrease current concentration, cylindrical electrodes are used. In a second embodiment, the liquid rheostat and an electrolyte storage container are disposed so as to surround a fluid transport pipe of a pumping system, the fluid being transported in the pipe serving to cool the electrolyte. The rheostat and storage container combined with the pipe provide a compact arrangement for saving space in a pump installation.
