Original Kurzfassung:
We present a sensor setup based on acoustic pressure waves allowing the determination of the acoustic viscosity and sound velocity of liquids. Compared to previously presented planar transducer based approaches, the proposed setup does not require the correction of spurious diffraction effects. Beside the basic sensor setup, a 1D-model and experimental data obtained with a first prototype device are discussed.
