Applicability of the PIV system for velocity field measurement inside the ultrasonic flowmeter

Ultrasonic (US) flow meters are devices for a fluid measurement using the ultrasonic principle. Current research project dealing with developing flowmeter an innovative channel shape. Previously work was aimed to topology optimization CFD methods. The final prototype has be analyzed experimentally verify velocity profiles in US section. obtained this region necessary as input sensor data evaluation. A particle image velocimetry (PIV) selected potentially suitable technique measurement. This paper presents development and initial testing of new experimental setup including track PIV system. Several modifications were realized during preparation setup. Finally, measurements performed simplified model results evaluated form area interest. most important knowledge about requirements on preparation. future will flowmeter.
