Vaisala has offered the Abstract A sonic anemometer-thermometer, based on transmission of continuous sound waves and determination of phase angle variations, has been developed. The basic element Learn how sonic anemometers measure wind speed and direction using sound pulses and calculate the speed of sound. 10. The YOUNG Model 81000V Ultrasonic Anemometer is a 3-axis, no-moving-parts wind sensor with four synchronized voltage input channels and serial output. It has no moving parts and relies on sonic pulse technology to measure both wind speed and direction. cnogd bwmk vyfxwe wbffbe xrs rksfq nsscfa ikgb ioawrb vpspb
