The sensor head incorporates three pairs of transducers orientated orthogonally across the measurement region. Each transducer in a pair alternately transmits and receives ultrasound pulses to and from its partner. By measuring the travel time of the pulse in both directions, the velocity component of the air flow along the line of each transducer pair is determined. A mathematical transformation converts the three wind vectors into U, V, W resultants."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0404" ; skos:note "accepted"@en ; skos:prefLabel "Sonic Gill R3-100 Research sonic anemometer"@en ; skos:related . skos:related . skos:narrower . skos:narrower .
