The principle of windsock
with the light cone is used to indicate wind direction, wind speed reference. By waterproof cloth windsock pneumatic system, the high quality stainless steel bearing, stainless steel wind lever of three parts. Cloth wind bag made of lightweight waterproof fabric has high flexibility, long service life, stainless steel bearings pneumatic system by stainless steel shaft, stainless steel pneumatic import high quality bearings, shaft, double waterproof parts, etc, with high precision, small wind resistance, slewing start wind speed is small, high reliability, long service life. By waterproof cloth windsock pneumatic system, the high quality stainless steel bearing, stainless steel wind lever of three parts.

standing in the instructions of the airport wind and roughly said wind speed of the device. For hanging in a certain height rod cone on the top of the bag. Has the wind the wind blowing into the mouth, make cone bottom indicating the whereabouts of the wind; Bag is the smaller the Angle, the greater the wind speed. With red and white stripes on the bag, easy to understand the wind direction and wind speed air pilots and ground controllers.
