Method and apparatus for determining properties of a pipeline, in particular the position of a branch of a sewage pipeline (US000010094659B2)

  • A method for determining properties of a pipeline includes feeding a sound wave signal at a predetermined feed point into the pipeline so that the sound wave signal propagates in an axial direction of the pipeline. The frequency spectrum of the transmitted sound wave signal has a frequency component or a spectral range with a maximum frequency that is smaller than the lower limit frequency for theA method for determining properties of a pipeline includes feeding a sound wave signal at a predetermined feed point into the pipeline so that the sound wave signal propagates in an axial direction of the pipeline. The frequency spectrum of the transmitted sound wave signal has a frequency component or a spectral range with a maximum frequency that is smaller than the lower limit frequency for the first upper mode. Reflected portions of the transmitted sound wave signal are detected as received sound wave signal and are evaluated with regard to the transmitted sound wave signal to determine at least the distance of each reflection site from the feed point.show moreshow less
