A6.4 - Wave Propagation Phenomena in Case of Clamp-On Ultrasonic Systems Applied on Liquid Filled Pipes

S. Wöckel, U. Hempel & J. Auge
Ultrasonic measurements are common techniques in industrial liquid analysis. Especially the non-invasive clamp-on configuration is an interesting approach due to its non-destructive nature and easy handling. Such a sensor can be mounted on existing reactors or pipes without stopping the process or rebuilding the system. However, such a technique often needs a sophisticated signal analysis in order to discriminate the measurement effect from disturbances caused by the multimodal sound propagation. The disturbing signals occur from...
