We demonstrate the performance of a newly developed viscosity measurement system, especially designed for liquid samples with low viscosities. The electromagnetically spinning (EMS) viscometer operated with a floating disk rotor enables the determination of viscosity with 1% accuracy for dilute aqueous solutions of various materials. In the article, we report the concentration dependence of the viscosity of a water/ethanol mixture. Accuracy required for a viscometer from the viewpoint of ultrasonic spectroscopy is also discussed.
