Ultrasonic transducer positioning system for clamp-on flowmeter applications

摘要

The positions of the ultrasonic transducers of clamp-on flowmeters have a determining influence on the precision and the accuracy of the measurement results. In this paper a transducer positioning system for ultrasonic clamp-on sensor applications is presented. It was designed in result of studies of the sensitivity and works automatically. The positioning system found an optimal transducer position for a special application by itself. So, the user can operate the clamp-on flowmeter with neither finding out some special information of the application process nor setting any parameters in the system before.
