... directly above the pitot-vane (Fig. 3 ). As air flows past the vorticity-meter, aerodynamic forces on the paddle surface create a torque that causes the paddle wheel to rotate. The tangential velocity of the air acting on the moment arm of the paddle wheel can be used to determine the angular velocity...
