Abstract

The effect of drops in the rotation wheel of the opto-electronic system of a commercial anemometer (Thies First Class Advanced) was studied. The output voltage of this anemometer was measured at different wind speeds during its calibration process, at 25 kHz sampling frequency along 25 s. The output frequency was calculated both ways: by counting pulses (CP) and by carrying out a Fast Fourier Transform (FFT). The errors of the anemometers transfer function based on both procedures are given in relation to the official (MEASNET) calibration. The effect of the sampling frequency is also analyzed together with the presence of oil drops. No effect of the oil drops was observed on calibrations carried out by extracting the anemometers transfer function with FFT. When using CP, results showed great differences between calibrations affected and not affected by the presence of oil drops in the rotation wheel of the opto-electronic system.
