APPARATUS AND METHOD FOR MEASURING THE WAVE PROPAGATION SPEED IN A FLUID-FILLED ELASTIC HOSE

摘要

The present invention relates to a wave propagation velocity measuring device and a measuring method inside the fluid-filled elastic hose, a plurality of fluidly-filled elastic hose that is arranged so that the longitudinal direction is aligned with the vertical direction and the bottom is blocked and a plurality of installed at a predetermined interval inside the elastic hose An acoustic module composed of four hydrophones; An excitation module extending to an upper end of the acoustic module to carry the fluid inside the elastic hose in the longitudinal direction of the elastic hose; A signal generator for supplying an excitation signal to the excitation module; It provides a wave propagation velocity measuring device inside the fluid-filled elastic hose, characterized in that it comprises a signal analyzer for receiving a signal from the hydrophone and analyzes the signal, there is no induction of unnecessary dynamic characteristics to ensure accurate wave propagation velocity It is to be measured.
