1. A system for locating an interface between a first material and a second material, comprising:

  • one or more acoustic sensing elements operatively arranged to measure a characteristic of one or more acoustic signals at a plurality of locations along a length of the one or more acoustic sensing elements; and

    an instrumentation unit coupled with the one or more acoustic sensing elements, the instrumentation unit operatively arranged to determine a difference between a first value of the characteristic measured at a first location of the plurality of locations and a second value of the characteristic measured at a second location of the plurality of locations for identifying the interface between the first material and the second material as being located between the first and second locations if the difference is greater than a preselected threshold amount.
