Patent ID: 7188426

Claim:
An inclination measurement and display device, comprising: a conductive chamber containing a fluid, wherein the conductive chamber comprises an annular chamber having an inner wall and an outer wall; a plurality of electrodes provided in the chamber, wherein at least three electrodes of said plurality of electrodes are partially immersed in the fluid, each of the at least three electrodes including more than one side, and more than one side of each of the at least three electrodes being partially immersed in the fluid, and wherein each of said plurality of electrodes is provided approximately equidistantly from the inner wall and the outer wall of the annular chamber; a processing module configured to measure an electrical characteristic between each of the plurality of electrodes and the conductive chamber and to determine an overall angle of inclination and the direction of inclination of the chamber; and a display for displaying a numerical value corresponding to the overall angle of inclination and an indication of the direction of inclination.
