In this paper, a practical sensing approach for monitoring the liquid-level in a container is presented. In this research we have developed a new structure sensor with three electrodes. When the container becomes inclined from vertical condition during measuring process, the liquid-level in the liquid container is determined correctly by detecting the change in capacitance between every two electrodes. In this process, a multidimensional regression equation based on experiment data is adopted. The result of this research proves that the designed sensor can be used to measure the liquid-level in the container unrelated to inclination.
