[Problem] To provide an ultrasonic physical properties measurement device that suppresses the generation of a secondary flow inside a cylinder, is more portable, and can suppress changes in physical properties. [Solution] An ultrasonic physical properties measurement devicethat: uses ultrasonic waves to measure the flow velocity profile of fluids that flow inside a cylinderby rotating the cylinderbackwards and forwards in a fixed cycle; and calculates the physical properties of fluid from the flow velocity profile. The cylinderhas an upper end surfaceand lower end surfacethat are penetrated such that fluid can flow therethrough; and comprises a rotation mechanismthat supports all or part of the cylinderin a state of immersion in the fluid and rotates the cylinderbackwards and forwards.
