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.
