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.Ultrasonic anemometer takes four ultrasonic sensors in the two-dimensional plane to send and receive ultrasonic signals; it is an instrument using the difference of the ultrasonic spread time in the air to measure wind speed and wind direction.Ultrasonic anemometer calculates the wind speed according to the difference of the sound spread time in the air; then calculates the temperature according to the physical relationship between temperature and sound speed.
