INFLUENCE OF VORTEX STRUCTURES ON PRESSURE AND ULTRASOUND IN VORTEX FLOW-METERS
V. Hans, H. Windorfer, S. Perpeet
Abstract:
Designing bluff-bodies for the ultrasonic vortex frequency measurement almost leads to very different geometries as they are used for the vortex detection method by pressure sensors. In some cases they have the same form but they are facing their backside to the inflow. The developing process is not only restricted by the demand for a constant Strouhal number and a strong linear dependency of the vortex frequency to the mean flow velocity but also by the vortex detection method.
