French LCJ Capteurs Ultrasonic Anemometer - SONIC-ANEMO-DVC

1. Description of French LCJ Capteurs Ultrasonic Anemometer SONIC-ANEMO-DVC:

Traditional anemometers have rotating mechanical parts. These moving parts are prone to damage.Ultrasonic SensorsDesigned to avoid any mechanical parts, ensuring more reliable operation. Ultrasonic sensors offer long-term stability without maintenance.
Sound is transmitted by the flowing object at the intersection. Electroacoustic sensors (1) communicate with each other using ultrasonic signals (2) along orthogonal axes, where wind speed (3) causes differences in sound transmission time. The CV7 sensor communicates 4 different tests between them, and the headwind obtained from the tests is used for calculation. The combined measurements calculate wind speed and wind direction based on the base axes. Temperature measurement is used for calibration. The sensor design reduces the influence of tilt angle (4) (the effect of sensor tilt can be partially corrected due to the spatial shape of the sensor).
The CV7 transmits 4 independent test data. A correctness check is used for the calculation of the headwind vector. This method gives a wind speed sensitivity of 0.15 m/s and excellent linearity up to 40 m/s.
