Flow velocity and direction is measured by observing the time-of-arrival difference of sound along the acoustic paths. It has also a compass in order to measure the earth\'s magnetic field, and a tilt sensor to measure the instrument\'s angle. Using these measurements, the direction of the instrument can be determined and consequently the flow direction.
