Two heated FT702LT wind sensors were installed on a met mast near Quebec Canada between January and May 2013. Over the test period nine significant heavy icing events were reported.
The TechnoCentre Éolien in Quebec monitored the performance continuously throughout the campaign and compared the results with unheated and heated mechanical cup anemometers and a conventional “time-of-flight” ultrasonic wind sensor.
The TechnoCentre Éolien reported that both FT sensors achieved >99.9998% data availability.*
