French LCJ Capteurs Ultrasonic Wind Speed Sensor - CV7-OEM

 1. Working Principle of French LCJ Capteurs Ultrasonic Wind Speed Sensor CV7-OEM:

Traditional anemometers have rotating mechanical parts, and these moving parts can easily damage the sensor. The ultrasonic sensor is designed to avoid any mechanical components to ensure optimal and more reliable operation. The ultrasonic wind speed sensor has long-term stability and requires no maintenance.
Sound (and ultrasound) is carried by the movement of the fluid it passes through. Electroacoustic transducers use ultrasonic signals to communicate with each other in pairs, determining the time difference of wave propagation caused by airflow along orthogonal axes. The CV7-OEM transducers communicate with each other, providing four independent measurements, while the headwind measurement vector is used for calculation. Combining these measurements calculates the wind speed and direction relative to the reference axis. Temperature measurement is used for calibration. The sensor design reduces the influence of tilt (based on the spatial shape, the influence of sensor tilt is partially corrected).
CV7_OEMUltrasonic Wind Speed SensorProvides 4 independent test data. Correctness checks are used for the calculation of the headwind vector. This method provides a wind speed sensitivity of 0.15m/s, with reliability and excellent linearity up to 40m/s.
