Electrolyte potential measuring apparatus
First Claim
1. A wheel electrode for use with a device for making electrical surveys of structures contained in electrolyte, said wheel electrode comprising:
- porous rim means including a dielectric rim structure having at least one recess in its axial surface and a plurality of apertures passing through the rim structure into the recess, and at least one porous member securable in said recess and having a predetermined rate of permeation whereby electrolyte solution provides a continuous conducting path through said porous members;
a chamber for containing the electrolytic solution which communicates with said porous rim means; and
metal electrode means in said chamber in contact with the electrolytic solution for sensing electrolytic voltage potentials in said electrolyte.

Abstract
The present invention relates to a wheel electrode suitable for use with a device for making an electrical survey of a structure contained in an electrolyte. The wheel electrode includes a chamber which contains electrolytic solution and a porous rim. The rim includes a dielectric rim structure having at least one recess in its axial surface, a plurality of apertures passing through the rim structure into the recess, and at least one porous member securable in the recess and having a predetermined rate of permeation. A metal electrode is positioned in the chamber in contact with the electrolytic solution. An elastic porous rim cover is securable about the rim for making contact with the electrolyte. The rim cover is adapted to carry an electrically conductive solution to the electrolyte during wheel rotation. Generating mechanisms are spaced about the wheel electrode at predetermined intervals for generating a series of electrical signals as the wheel electrode rotates. A count of these signals is indicative of the distance travelled by the wheel electrode.
