Utilizing the transient response of an acoustic transmission setup utilizing pressure waves to determine physical liquid parameters

Description

Ultrasonic sensors are suitable for the determination of physical fluid parameters like e.g., viscosity, mass density and sound velocity. In this contribution we present the concept of a recently devised sensor setup utilizing transient pressure waves to determine the longitudinal viscosity of fluids. Besides the basic sensor setup an according 1D-model, an implemented PSPICE model of the whole sensor system and a comparison of simulation results to measurement results obtained with a prototype device are presented.
