ULTRASONIC ANEMOMETER VS. ANEMOMETER + WIND VANE :

Why choose an ultrasonic anemometer over its mechanical "ancestor"? First of all, it is important to understand how an ultrasonic anemometer works in order to compare it. 

Pairs of electromagnetic transducers communicate in pairs, alternating the role of transmitter and receiver. When the wind passes through the signal emitted between two transducers, the reception time of the sound signal is slowed down. From this measurement, wind speed and wind direction can be deduced. 

There is no mechanical movement or moving parts, reducing the risk of wear and tear and increasing the reliability of the equipment.

Another induced phenomenon: there is no inertia, the data are processed in a very short time, giving real time and very accurate information. Indeed, a wind vane and a classical anemometer are subject to a certain inertia due to their mechanical mode of operation.

Advantages of the ultrasonic anemometer:

• Linear data
• Sensitivity of 0.25 kn
• Accuracy up to 80 kn
• Reliable and maintenance-free
• Ultra compact and light
