There’re two versions of WINDCRANE, mini and max. They share the same technological design and their accuracy is exactly the same. WINDCRANE is designed to comply with the IEC-61400, which are the specs for wind turbine standards. Why the IEC-61400? Because they have one of the highest standards for measuring wind speed on and off site. These are better than 1% accuracy and a resolution better than 0.1m/s, also data should be sampled at least at 1Hz. WINDCRANE is accuracy is better than 0.001% for its wind speed input sensors at low wind speeds and better than 0.007% accurate for high wind speeds.
