High-resolution acoustic pipe condition assessment using in-bracket pipe excitation
Methods, systems, and computer-readable storage media for performing high-resolution assessment of the condition of pipes of a fluid distribution system using in-bracket excitation. Acoustical impulses are generated in a pipe at two excitation locations along the pipe while signal data is recorded from two acoustic sensors, at least one of the excitation locations being located in-bracket of the two acoustic sensors. A first time delay between the arrival of the acoustical impulses at the two acoustic sensors is computed from the signal data recorded during generation of the impulses at the first excitation location, and a second time delay between the arrival of the impulses at the two sensors is computed from the signal data recorded during generation of the impulses at the second excitation location. An acoustic propagation velocity is computed for a section of the pipe defined by the first and second excitation location based on the first time delay, the second time delay, and a distance between the excitation locations, and a condition of the section of pipe is determined from the computed acoustic propagation velocity.
