Patent number: 11474073Abstract: Methods for noninvasive determination of acoustical properties of flowing in pipes having a large ratio (>10) of pipe diameter to wall thickness, and in highly attenuating fluids are described. When vibrations are excited on the outer surface of the wall of a pipe, the resulting vibrations propagate directly through the wall in a normal direction and through the pipe wall as guided waves, appearing on the opposite side of the pipe. This dual path propagation through pipes, where guided waves take the circumferential path in the wall of the pipe and may interfere with the time of-flight measurement obtained from the direct path through the fluid, is at least in part resolved by subtracting the signal from the guided wave from the combined signal, thereby permitting improved observation of the direct path propagation through the fluid.Type: GrantFiled: July 20, 2017Date of Patent: October 18, 2022Assignee: TRIAD NATIONAL SECURITY, LLCInventors: Dipen N. Sinha, Cristian Pantea, Blake T. Sturtevant, Anirban Chaudhuri
