Wind Meter 1590-PK-020/W Gill Instruments Vietnam
The WindMaster measures the times taken for an ultrasonic pulse of sound to travel from an upper transducer to the opposite lower transducer, and compares it with the time for a pulse to travel from lower to upper transducer.
Likewise times are compared between each of the other upper and lower transducers.
As Figure 1 shows, the air velocity along the axis between each pair of transducers can then be calculated from the times of flight on each axis.
This calculation is independent of factors such as temperature.
From the three axis velocities, the wind speed is calculated, as either signed U, V, and W, or as Polar and W.
