2.0 INTRODUCTION MODEL 81000V The Young Model 81000V measures three dimensional wind velocity ULTRASONIC ANEMOMETER and speed of sound based on the transit time of ultrasonic acoustic signals. Sonic temperature is derived from speed of sound which is corrected for crosswind effects. Four voltage input channels measure DC signals from external sensors concurrent with wind measurements. -
