The cup anemometer has a standardized configuration of three cups, as the 3-cup anemometer has become the most efficient solution when compared to the 4-cup anemometer (this was the initial configuration of the cup anemometer developed in the XIX century).

The cup anemometer overspeeding phenomenon consists of a quicker response upon wind flow acceleration than the one obtained after a wind flow deceleration. This causes an overrun of the cup anemometer (that is, an overestimation of the measured wind speed) in turbulent flows.
This effect was already described in by Brazier [85,86].Cited by: The effect of cup anemometer shape parameters, such as the cups shape, their size, and their center rotation radius, was experimentally analyzed.
This analysis was based on both the calibration constants of the transfer function and the most important harmonic term of the rotors movement, which due to the cup anemometer design is the third one.
This harmonic analysis represents Cited by: The influence of anemometer rotor shape parameters, such as the cups’ front area or their center rotation radius on the anemometer’s performance was analyzed.
This analysis was based on calibrations performed on two different anemometers (one based on magnet system output signal, and the other one based on an opto-electronic system output signal), tested with 21 different rotors.

The results of several research campaigns investigating cup anemometer performance carried out since at the IDR/UPM Institute are included in the present paper.
Several analysis of large series of calibrations were done by studying the effect of the rotor’s geometry, climatic conditions during calibration, and anemometers’ ageing. More specific testing campaigns were done regarding Cited by: An anemometer is a device used for measuring wind speed and is also a common weather station instrument.
The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in first known description of an anemometer was given by Leon Battista Alberti in Originally, a four-cup mounting was used (Robinson type), but the dynamic response of three cups (Patterson type) is better and the majority of instruments follow this finding.
The maximum torque produced by a single cup does not occur when the wind blows directly into the concavity of the cup but when it forms an angle of about 45 degrees. This banner text can have markup. web; books; video; audio; software; images; Toggle navigation.
Tests instituted with the object of determining the pressure which the wind exerts on the cup of a "Robinson" anemometer have shown that when the breeze blows into the concave side of the cup, its effect is rather more than three times as strong as when it blows against the convex side.
Both analytical and experimental research on cup anemometer behavior has shown the correlation between anemometer transfer function (see Equation (1), below) and cup center rotation radius, Rrc.
However, some differences have also been highlighted between the results obtained using the two methods [76,77], see Figure 2.
