ABSTRACT:
A wind measuring system can be used in meterology for a more accurate and reliable measurement of the velocity and the direction of an air current. The system has a sensor for velocity and a wind vane with sensors for horizontal and vertical wind directions. Depending on the velocity of the air current, a reference disc is rotated which generates pulses for each revolution. Horizontal air direction pressure is transmitted to bearing axles and a gear to cause rotational motion of a transducer for horizontal direction. Vertical air direction pressure rotates a transducer for vertical direction. The phase difference of the pulses from the transducers produces time delays which are recorded by a unit for electronic processing of the information. An output is generated indicating wind speed and direction.
