Beschreibung
Zusammenfassung:	The invention provides a flow velocity detection method, equipment and device, and the method comprises the steps: obtaining at least two groups of initial flow velocities obtained through the detection of at least two groups of ultrasonic transducers, and enabling each group of ultrasonic transducers to correspond to one group of initial flow velocities, the emission directions of each group of ultrasonic transducers are crossed, and a first included angle between the emission direction of each group of ultrasonic transducers and the flowing direction of fluid to be detected is an acute angle; determining the flow velocity component of each group of initial flow velocity in the axial direction of the tube cavity and the flow velocity component of each group of initial flow velocity in the radial direction of the tube cavity; and determining the flow velocity of the fluid to be measured by using the flow velocity component in the axial direction of the tube cavity and the flow velocity component in the radial
