ABSTRACT:
In one embodiment of the present invention, a method for measuring fluid level use a sensor comprising a first plate having continuous electrically conductive material and a second plate having electrically conductive material disposed in segments, the electrically conductive material of the first plate in opposition to the electrically conductive material of the second plate. The method comprises immersing the sensor in the fluid with at least one segment completely immersed in the fluid and at least one said segment completely out of the fluid. The method also includes sequentially energizing the segments. Further, the method includes detecting times of voltage transitions of a first signal at the first plate, relative to the sequential energizing of the segments, as an indication of fluid level.
