Mechanical anemometers have worked well for years but the rigorous duty on wind turbines may call for a more reliable sensor. Accurate measurements of wind speed and direction from reliable equipment are more important than ever in today’s competitive North American wind industry. Demand for reliable wind sensors is high and manufacturers are responding with…

Cup anemometers can generate inaccurate wind-speed values in gusty periods, and should one freeze, its turbine may have to shut down. One solution is an ultrasonic anemometer, like the Ventus UMB 8371 with a 240W heater. This unit provides precise and maintenance-free measurements of wind velocity and direction.         Ventus belongs to Lufft’s WS family…
