• High linearity and accuracy with < 1 m distance constant


Measurement standards
Range Resolution Accuracy Sampling rate
Wind speed 0-100 m/s 0.01 m/s < 2 % of measured value (0.3 – 50 m/s) or ±0.05 m/s (4-16 m/s) with MEASNET cal. 2 pulses per revolution
Wind direction 0-360° 5° (no dead-spot) 10 Hz /1Hz avg. out
Linearity R2 > 0.99995
Tilt angle sensitivity Cosine response, see graph. (Horizontal wind speed measurement)
