Application for Ultrasonic Anemometer Sensor:

 

Ultrasonic anemometer has all digital signal detection, high accuracy, automatically heating ability to remove snow and ice .It is the anemometer with real-time measurement of wind speed, wind direction and acoustic temperature.A typical ultrasonic anemometer consists of 2 pairs of ultrasonic transducers mounted at right angles to one another as shown in the figure below. Each sensor is capable to transmit and receive ultrasonic pulses. The physical distance between the opposite facing sensors is fixed and known. During operation, the time taken for an ultrasonic pulse of sound to travel from the North (N) transducer to the South (S) transducer is compared to the time for a pulse to travel from S to N transducer. If there were no wind blowing, the two times should exactly match. Otherwise, the sound wave traveling with the wind should arrive earlier than the sound traveling against it. For example, if there is a wind blowing to N, the N to S travel time would be more compared to the S to N travel time. The difference in the time of flight can give the relative speed of wind along NS axis. Similarly, flight times are also compared along the East-West and West-East directions to compute the wind velocity along the EW axis. The two rectangular velocity components of the wind are then combined to compute the wind vector with a resultant sum and an angle of wind velocity. The sensor arrangement shown below gives only the horizontal wind speed. Measuring a three dimensional wind speed requires sensor arrangements along the vertical direction too.
