ACOUSTIC SENSING SYSTEM FOR DETERMINING AN INTERFACE BETWEEN TWO MATERIALS

摘要

A system for locating an interface between a first material and a second material including 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 thereof. An instrumentation unit is coupled with the one or more acoustic sensing elements, and arranged to determine a difference between at least a first value of the characteristic measured at a first location 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. A method of locating an interface is also included.
