A sensor apparatus for determining fluid levels and pressures in a fluid-containing vessel wherein the sensor apparatus comprises a mounting member having a fluid passageway positioned therein; a pressure sensor in operative contact with one end of the mounting member and a pressure fluctuation dampening device operatively positioned on the other end of the mounting member. The dampening device comprises an arrangement of fluid passageways arranged so that the fluid passageway through the mounting member substantially perpendicularly intersects a second fluid passageway intermediate the ends of the second fluid passageway with the second fluid passageway being intersected at each of its ends by third and fourth fluid passageways.

Level sensor

An improved process and apparatus for electrolyzing ions in a liquid electrolyte wherein the electrolyte is covered by an immiscible liquid of low conductivity and whereby the entrainment of said immiscible liquid in said electrolyte is prevented.

Electrolysis process and apparatus

An improved process and apparatus for electrolysis of a high purity metal from an aqueous pregnant liquor acid electrolyte at high efficiency and high current density in the presence of impurities. In one embodiment the electrolysis cell employed in such process is provided with a fluid cover.
