Ultrasonic guided waves can propagate over long distances in process pipe and have demonstrated excellent sensitivity to viscous coatings on the inner surface of piping commonly used in the processing of dairy products. This technology shows excellent potential to help upgrade plant maintenance from a time based to a condition based schedule. The design, fabrication, and installation of new piezopolymer guided wave sensors is discussed with emphasis on their affordability.
