Anemometers measure the horizontal wind speed (velocity). This parameter is crucial for any wind site assessment. Cup anemometers are the general standard type of anemometer. They are robust and res…
Wind vanes determine the wind direction. The evaluation of the wind direction ensures the best possible position of wind turbines. It is essential that a wind vane covers an entire 360° degree radi…
Temperature sensors measure air temperature, while humidity sensors measure air humidity. Both sensors are often applied in combination to reduce cost. The calculation of the air humidity does not d…
Air pressure sensors (barometers) measure the air pressure. Air pressure and air temperature should be evaluated for an accurate wind site assessment, although this data could be obtained from nearb…
Precipitation sensors are designed to measure the quantity and intensity of precipitation striking the earth’s surface. Precipitation is best measured with a tipping bucket device. Precipitation, co…
Ultrasonic anemometers measure the horizontal wind speed and direction as well as the acoustic virtual temperature. High Power Consumption Because of their high power consumption, a connection to ma…
Pyranometers (global radiation sensors) measure global radiation. They are also used as reference instruments due to their measurement precision. The use of this sensor is crucial for measurements w…
Remote sensing systems have become more and more popular in the wind industry as a supplement to the traditional met mast. Remote sensing systems can be applied to complement a wind site assessment …
