acoustic method and apparatus for detecting or characterising a medium contained in a container

摘要

acoustic method and apparatus for detecting or characterising a medium contained in a structure, acoustic method for detecting a presence of hydrate in an internal cavity of a hydrocarbon pipeline, acoustic apparatus for the detection of a hydrate presence in a hydrocarbon pipe, and food-utator programme product an acoustic method and apparatus for the detection or characterisation of a medium included in a structure. Typically, the structure is a container, such as a tube line for transporting oil,gas or condensate from hydrocarbons. a broadband acoustic energy pulse is emitted in the direction of said structure by a first transducer medium. a retort signal is generated by a second acoustic energy transducer means taken over from said structure in response to said emission. a retort signal spectrum representing acoustic spectral components of said acoustic energy taken over from said structure is derived from said retort signal, and said medium is detected or characterized applying an algorithm for detection or characterization of a right signal processing medium to said right signal spectrum.
