Abstract
A fuel level probe has a series of stacked, annular capacitors, the capacitance of which changes with the dielectric constant of the fluid in which they are immersed. A multiplexer provides sequential measurement of each capacitor to determine a step change in capacitance and hence fluid levels based on the time at which the capacitance changes.
