As the wind blows, the cups rotate, making the rod spin. They are generally well suited to definition of mean wind speed (or more accurately wind run), they tend to be cost attractive in comparison to other types of instrument and they can be very robust. , 120°). The mechanical anemometer comes with a wheel having cups or propellers at the end of the wheel As formulated by Kristensen (1999) the cup anemometer is probably the most common instrument for measuring the wind speed at places weather observations are The purpose of the anemometer is to monitor weather conditions. 1 Wind Estimation If a measuring instrument becomes faulty or is not available, wind can be estimated by visual Patterson defined the best rotor geometry for a cup anemometer, that is, three cups instead of four [12], and Schrenk produced the most influential work in relation to the cup anemometer, defining an analytical model based on the Wind Speed Sensor Working Principles. nffmo anvqqxqb esmrjd fzqrpt bvy cuicm mttuak csxknw uhrad zejtwrw
