Proc. Eurosensors XXVI
Physical fluid parameters like viscosity, mass density and sound velocity can be determined utilizing ultrasonic
sensors. In this article, we introduce the concept for a recently devised transmission based sensor utilizing pressure
waves to determine the longitudinal viscosity of the fluid in the sample chamber. We present the basic sensor setup
an according 1D-model for the whole setup and compare simulation results with measurement results obtained with a
first prototype device.
