METHOD AND APPARATUS FOR MEASURING THE PHASE CHANGE OF A SOUND WAVE PROPAGATING THROUGH A CONDUIT

摘要

A system for measuring the superposition of a plurality of sound waves propagating within a conduit containing a fluid having a plurality of transducers positioned substantially parallel to the flow direction along the external surface of the conduit. The system includes means for modeling the superposition of a plurality of sound waves as they propagate within the conduit.
