Mathematical Analysis of the Effect of Rotor Geometry on Cup Anemometer Response

Figure 2

Simplified anemometer factor, , as a function of the ratio of the cup radius to the cup center rotation radius, ( ), regarding the calibrations performed on the Climatronics 100075 anemometer (Cl 100075; white symbols) and the Ornytion 107A anemometer (Ory 107A; grey symbols) [21]. Both were equipped with  mm cups (rhombi),  mm cups (circles),  mm cups (squares),  mm cups (triangles), and  mm cups (crosses).
