Abstract
Flow sensors based on the principle of electromagnetic induction were
investigated as alternatives to commonly used mechanical devices utilizing
rotors and propellers. Prototype sensors were constructed showing considerable
promise. Measurement accuracy in excess of .01 knot seems
feasible with devices suited to long term battery operation. The inertial
effects and many of the reliability problems inherent in moving part
devices would be overcome by use of an electromagnetic sensor.
