Principle of operation: how the equipment works The sound, the ultrasonic sound is conveyed by the movement of the fluid in which it crosses. The electroaccoustic transducers communicate between themselves two by two by ultrasonic signals determine, following the orthogonal axes, the wave transit time differences induced by the air flow The measurements are combined in an integrated calculator in order to establish the wind module and its direction in relation to a reference axis.

Installation Determine a place free from obstacles to the wind, generally at the top of the mast. Direct the stirrup of fixation so that CV7 is steered forward to the ship. Fix the stirrup following the drillings defined by the joined size. A better precision of the axis can be obtained by using the program of correction of angle.
