Ultrasonic Anemometer-Vane with USB connection NMEA0183

The CV7 vane anemometer is an ultrasonic anemometer made in France. This anemometer has proven itself in marine applications, and is renowned for its robustness in the naval sector as well as for its accuracy in the competitive sailing sector. 

Sonic wind sensors are static wind vanes with no rotating parts. Thus, the CV7 wind sensor is unobtrusive due to its small size and the absence of moving parts that do not attract the eye.

Configurable wind sensor

This sonic sensor is configurable, the following parameters can be adjusted: angle correction, smoothing time constant, measurement units, interface format. The configuration of the sonic anemometer is stored in a non-volatile EEPROM.

USB connection

The sensor can be operated directly from a PC via the USB connection provided. Compared to the basic version CV7-V, the anemometer additionally includes a USB box interface with an opto-coupled data input, a 12 VDC power supply output for the sensor and a USB port (FTDI driver) type A cord.

The weather data can be viewed with the free StatFixMETEO visualisation software. The paid version also allows the data to be saved in a daily file.

Made in France

The CV7 vane anemometers are manufactured in France in the Nantes region, allowing for a fast and efficient after sales service. This proximity also allows the manufacturer to adapt these products to your specific needs, so don't hesitate to contact us. 

The anemometers are subject to stringent quality controls throughout the manufacturing process.
