Abstract: The present subject relates generally to acoustic inspection probe guidance or tracking, such as facilitating free-hand scanning of an acoustic probe assembly for performing acoustic inspection. For example, using an acoustic inspection probe assembly, an acoustic telemetry signal can be transmitted, such as separately from acoustic pulses or echoes used for acoustic inspection. Using at least one electroacoustic receiver, the acoustic telemetry signal can be received and using the received representation of the acoustic telemetry signal, at least one of (1) a position of the acoustic probe assembly relative to a reference position or (2) an orientation of the acoustic probe assembly in relation to a reference orientation can be determined. An indicium can be provided to a user indicative of at least one of (1) the determined position or (2) the determined orientation.

Abstract: Methods, systems, and computer-readable storage media for providing high-resolution assessment of the condition of pipes of a fluid distribution down to the individual pipe stick. An acoustic sensor is placed in acoustical communication with a pipe at one end of a target segment. An acoustical wave is generated in the pipe at a first out-of-bracket excitation location while signal data is recorded from the acoustic sensor. Timing information regarding the arrival at the acoustic sensor of reflections of the acoustic wave from pipe joints in the target segment is extracted from the recorded signal data, and a time delay between reflections from consecutive pipe joints is computed. An acoustic propagation velocity in a pipe stick between the consecutive pipe joints is then computed based on the time delay and a length of the pipe stick. A condition of the pipe stick is determined based on the computed acoustic propagation velocity.

Abstract: In some implementations, a method includes receiving data characterizing a plurality of acoustic signals detected at a plurality of segments of an industrial system. A first data subset of the received data is associated with a first acoustic signal detected at a first segment of the plurality of segments and a second data subset of the received data is associated with a second acoustic signal detected at a second segment of the plurality of segments. The method also includes assigning a first characteristic color to the first data subset based on a first time of propagation and an amplitude of the first acoustic signal, and assigning a second characteristic color to the second data subset based on a second time of propagation and amplitude of the second acoustic signal.
