Abstract
A fuel energy analysis system is disclosed utilizing a first hydrostatic sensor, calibrated to specific fuel tank geometries, to monitor fuel quantity; and an additional hydrostatic sensor located at a different geometric height from said first sensor, allowing determination of specific gravity through hydrostatic pressure, and thereafter computation of energy content as a function of mass. This system is particularly suitable for harsh environments such as vehicular applications wherein the quality of fuel input to a tank may frequently vary, and is readily corrected for fluid motion in the tank, by the addition of additional sensors in conjunction with baffles.
