Abstract: A system, device, and method include a cell-powered first electronic device for monitoring two or more electrolytic cells is powered using electrical potential imposed across the electrolytic cells. The potential is voltage-boosted to accomplish this task. If the electrical potential imposed across the cells is insufficient, the device can also be battery-powered. In any event, this device is in communication with one or more sensors in the electrolytic cells, as well as a second electronic device, and the first and second electronic devices wirelessly communicate. More specifically, the first electronic device wireless transmits data signals to the second electronic device, which receives the same. The first and second electronic devices are physically remote from one another, and they communicate over a private or public network, preferably using spread spectrum technology.

Abstract: A method of detecting shorts and bad contacts in an electrolytic cell, the cell comprising a housing, electrolyte and at least one anode/cathode pair, the housing comprising an electrolyte in-flow side and an electrolyte out-flow side and electrical transmission means, the anode/cathode pair, electrolyte and electrical transmission means in electrical communication with one another, the method comprising: A. Passing an electric current of pre-determined amperage through the cell; B. Measuring the voltage drop across the cell at the electrolyte in-flow side of the housing and at the electrolyte out-flow side of the housing, C. Comparing the electrolyte in-flow side voltage against the electrolyte out-flow side voltage, and D. Comparing the electrolyte in-flow and out-flow side voltages against a calculated or estimated target voltage.
