DISPERSION COMPENSATION TECHNIQUE FOR DIFFERENTIAL SONAR MEASUREMENT - DENSITY METER |
摘要 |
The present invention provides a novel technique for canceling substantially the effects of dispersion when two speed of sound (SOS) measurements are required on the materials within a pipe to perform a calculation or derive certain characteristics about the materials flowing in the pipe. According to some embodiments of the present invention, the apparatus may comprise a signal processor configured to receive signals containing information about two speed of sound measurements having two sets of data related to materials within a pipe; and process the two sets of data simultaneously and determine a ridge point by point difference in order to cancel substantially effects of dispersion. |
