Abstract
A method and an apparatus for detecting, locating, and quantifying contamination in a fluid flow system like a pipe or duct. This characterization technique uses a conservative and one or more interactive tracers that are injected into the fluid flow system and then monitored at another location in the system. Detection, location, and quantification are accomplished by analysis of the characteristic features of measured curves of tracer concentration.
