A probe with no-moving parts for measuring the vorticity of a flowing fluid. The probe consists of an elongated, cylindrical stem member having one end fixedly mounted, means for imparting to the other end of the stem member a torque which is proportional to the vorticity of a flowing fluid, and means for measuring the imparted torque. In a specific embodiment the torque imparting means consists of fins attached to the other end of the stem member and the measuring means consists of strain gauges oppositely wound around the circumference of the stem member. The strain gauge outputs indicate the torque being applied to the stem, and therefore provide signals proportional to the vorticity of the flowing fluid.
