DESIGN ASPECTS OF ULTRASONIC MEASUREMENT CONFIGURATION IN VORTEX SHEDDING FLOW-METERS

H. Windorfer, V. Hans

Abstract

The high sensitivity of ultrasound on small turbulences leads to new considerations on the dimensioning of bluff-bodies and the positioning of the ultrasound beam. Smaller dimensions cause smaller pressure loss, higher vortex frequencies and higher signal resolution. The high sensitivity of ultrasound on modulating influences admits the measurement not only behind but also in front of the bluff-body with the advantage of better signal-to-noise ratio.
