The shown values have been measured while the calibration with the auxiliary wind tunnel in many hours. Just the mechanical dimensions of the selected construction appear here as unfavorable. The measurement and correction of the wind speed and direction dependent reductions in an ultrasonic anemometer represent a large challenge. Picture: Anemometer within the wind tunnel.Ĭorrection of wind speed (caused by turbulence due to the sound converters itself) Picture: Look through the wind tunnel onto the anemometer.

Ultrasonic Anemometer (Prototype I) Idea and result The last supplement to website: 31st of August 2022 With interest, a look about the whole page is recommendable now and then. This page is extended over and over again at the most different places. The work on the second prototype is finished now. Maybe somebody also likes to improve my translation into the English language. I am glad about corrections or suggestions. However, besides, I have tried to provide references (often Wikipedia) for an explanation. But I cannot deepen the mathematical bases further. However, nobody should hold this from reading this small article. The mathematical methods can be only mentioned in this shortness and assume to the understanding generally an appropriate university study. This page is no construction manual, but the short description of the development created over a time of 10 years. At advancement, you can see the innovations with the second version. Two different prototypes have originated. Please read in addition also my conclusion at the end of this page. This prototype instrument is operating equal good as several commercial devices. This side describes my own development of a precision measuring ultrasonic wind sensor. Ultrasonic anemometer (Ultrasonic wind sensor) Ultrasonic Anemometer (Wind speed and direction)
