Abstract
A rotational cup anemometer with an improved design for the cups is herein disclosed. The anemometer has a rotational assembly with essentially identical cups. Each cup is asymmetric to the plane of rotation. Each cup has a central axis parallel to the plane of rotation. Each cup is asymmetric to the central axis of the cup. Each cup may have a lower surface extension that provides a lifting surface, contributes to an upward force as the rotational assembly is rotated or affects presented frontal area at wind angles. A rotation rate of the rotational assembly as a function of wind angle is closer to the ideal cosine curve as compared to a standard anemometer, for a range of wind angles. Rotating the rotational assembly in a wind parallel to the plane of rotation produces a net upward force on the cups that offsets the weight of the rotational assembly.
