ABSTRACT:
A wind velocity indicator is disclosed in which the force of air impinging on a lower surface of a moveable rotating disk causes the disk to ascend a shaft to a position proportional to the wind speed. A system for incrementally adding weights to the top of the disk is provided in order that the altitude of the disk along the shaft represent an indication of wind speed. The system is further provided with visual means for permitting the indicated wind speed to be remotely determined.
