Resumen
The method involves changing vector speed of wind flow during time of tripping of pulses of ultrasounds. The vector speed is measured throughout an acoustic footpath by a non-instantaneous average model. Projection of the vector speed is determined according to the acoustic footpath. The vector speed is changed during the time between firing of two consecutive pulses. A sensor is utilized to consider average values of the vector speed during the measurement process, temperature, composition of fluid and discreet process of speed data.
