Abstract
This distant wind meter can be used wherever the transmitter and the receiving station are in an unobstructed view. The transmitter of the wind meter consists of a wind vane, a cup anemometer, a clock with electric contacts and a oscillator. The power of the oscillator is about 0.3 watt.
The carrier wave of ultra short wave is modulated by a low frequency wave which is varied by the motion of the wind vane. The indicator of the wind direction of the vibrating reed frequency meter is directly connected with the receiver. The wind velocity is measured through the audio-signal that is generated every 100 meter range of wind course.
