CD-Proceedings of the GMe Forum 2011
We report on a concept for a fluid sensor utilizing pressure waves for sensing the fluid properties (e.g. viscosity, sound of speed). The detection of fluid properties is of importance for many technical processes. Requirements for such sensors are small size, robustness, lightweight and a reasonable price. An approach utilizing pressure instead of shear waves is introduced. With this approach it is possible to overcome the drawback of the small penetration depth of shear waves in liquids. The theoretical background, a simple 1D model, simulation results and first measurement results are presented.
