ABSTRACT:
An apparatus for measuring wind speed and direction includes: a wind vane having a permanent magnet, an anemometer having a permanent magnet and a ferromagnetic member, and a stationary housing having radially and axially mounted reed switches. As the anemometer spins, the anemometer magnet closes the radially mounted reed switch once per revolution. This produces a signal having a frequency proportional to wind speed. The wind vane magnet rotates around the housing to a point determined by the wind direction, producing enough flux to keep the axially mounted reed switch closed. The ferromagnetic member is interposed between the magnet in the wind vane and the axially mounted reed switch once per revolution. This draws flux away from the axially mounted reed switch, allowing it to open. The result is a second output signal having a phase difference, relative to the first output signal, that depends on the wind direction. The direction of the fluid flow is determined by computing the phase difference. The housing has a mounting assembly including tapered, grooved mounting members, and a locking collar with a circumferential land to engage the grooves. The housing may be mounted at any azimuthal angle. Calibration compensates for the mounting angle.
