Title:A three PZT setup for determining physical liquid properties utilizing acoustic pressure wavesAuthor(s):Hannes Antlinger, Stefan Clara, Bernhard Jakoby, Roman Beigelbeck, Samir Cerimovic, Franz KeplingerAbstract:Abstract—Sensors utilizing acoustic pressure waves are suitable for the determination of physical liquid parameters (e.g. mass density, speed of sound and viscosity). In our contribution we introduce a sensor setup based on three PZT transducers immersed in a sample fluid utilizing transient pressure waves to determine the longitudinal viscosity of the fluid. We discuss the basic sensor setup, an according 1D-model and present a prototype device and experimental data obtained with this setup.Booktitle:2013 IEEE SENSORS ProceedingsISBN:978-1-4673-4642-9Page Reference:page 758-761, 4 page(s)Publishing:11/2013
