Methods and systems are disclosed for using time domain reflectometry to determine the identity of a fluid in a vessel, and to determine whether the quality of a fluid in a vessel is within acceptable parameters. Methods include identifying a fluid by comparing a derived characteristic of a fluid to a reference characteristic, determining the quality of a fluid by determining if a derived characteristic is within an acceptable quality range, monitoring a fluid for a dynamic change in quality or state, and identifying a fluid by comparing a transition reflection waveform to a reference signature transition. The methods are implemented in systems for identifying a fluid layer in a vessel, such as fuel, free liquid water or ice, detecting misfueling or fuel contamination, and detecting fluid state changes, such as the formation of ice. |
