Abstract
An anemometer for measuring the velocity of a fluid. The anemometer has a pivotally mounted shaft with a drag element mounted thereon for exposure to the fluid. Electromagnets are orthogonally located adjacent to a ferrite block on the shaft, and changes in position of the shaft are sensed by changes in voltage across the electromagnets. A controller senses these voltage changes and applies current to the electromagnets to produce electromagnetic force to restore the position of the shaft and balance the fluid force on the drag element. A micro-processor computes fluid speed and direction from the current applied to the electromagnets.
