Original Kurzfassung:
Ultrasonic sensors can be used to determine physical fluid parameters like viscosity, density, and speed of sound. In this
contribution, we present the concept for an integrated sensor utilizing pressure waves to sense the bulk of the fluid. Longitudinal
viscosity and speed of sound can be determined using interference effects whereas the acoustic impedance of the liquid can be
sensed if interference is suppressed by introducing a wedge reflector in the setup.
