Pulsonic delivered more than 70 Alizia 310 wind sensors (adapted to freezing conditions) and 280 standard Alizia 312 sensors to Meteo-France. These sensors are set up on the sites of the Meteo-France ground observation network.
The Alizia 310 sensors (adapted to freezing conditions), use one ultrasonic anemometer which can be heated easily. These equipments are mainly intended to be set up on mountains.
The standard Alizia 312 sensor includes one anemometer with cups and one vane with a flag in carbon fibre. They are powered by one solar panel.
The sensors make speed and direction measurements twice a second and make the necessary calculations to the wind according to the WMO* and ICAO** rules.
Main calculations: Wind maximum speed and its associated direction, calculated over a period of one and 10 minutes. Calculated variation of wind speed and direction over a period of 10 minutes Wind average speed and the argument of the wind average vector over a period of 2 and 10 minutes Passed wind over a period of one minute Standard deviation of wind speed and direction over a period of 10 minutes Squall indicator
The intelligent sensors manage the CIBUS protocol and transmit data to a display showing the instantaneous values of wind
