| Definition | Triaxial sonic anemometer with asymmetric head and a data output rate of 100Hz. The sensor head of the anemometer consists of three pairs of transducers orientated at different angles across the measurement region. Each pair of transducers act alternately as transmitters and receivers, sending pulses of ultrasound between them. By measuring the time of flight of the pulse in both directions, the velocity component of the air flow along the line of the transducer pair can be determined. This measurement is carried out for each of the three transducer pairs in turn. A mathematical transformation is then performed, to convert the resulting three wind vectors into U,V,W format. |
