Wind speed and direction condition the evolution of meteorological conditions. They are data we also use in the aeronautical, naval, and construction industries.
Depending on the desired precision and the usage environment, METEO OMNIUM determines the type of wind gauge and/or weathercock to install. The two sensors can sometimes be combined in one device.
Various types of wind speed sensors can be installed :
- Cup anemometer (Robinson's) : three cups mounted on horizontal brackets, fixed to a vertical axis equipped with a rotation counter. Wind speed is conditional to the anemometer's rotation speed.
- Vane anemometer : associated with a weathercock, it determines wind direction.
- Ultrasonic anemometer : this device allows measuring violent winds and can be used in difficult conditions.
In meteorology, we differentiate instantaneous winds (measured every 3 seconds), and average winds (measured every 10 minutes). Wind shear corresponds to a sudden increase in instantaneous wind.
Many types of wind direction sensors and weathercocks can be installed to determine wind origin and direction
