  • Cable testing, cable length, and liquid level determination system utilizing a standing wave reflectometer
    Publication number: 20030222654
    Abstract: A standing wave reflectometer (SWR) that generates a standing wave on a conductor, receives a reflected standing wave, converts the reflected standing wave to a digital representation, determines a plurality of curve fitted minima of the digital representation of the reflected standing wave, and determines a location along the conductor where there is an interruption in uniformity such as at the end of the conductor, or where the conductor is touching a liquid, and thereby determine integrity of the conductor, length of the conductor, or a level of the liquid.
