When the direction of flow speed is measured, in the interrogation volume formed as a sphere by an increasing ultrasonic wave being constituted from the average size, all directions are the same. An approximate means square spatial gradient of the back-scattering signal is measured by being supplied to measure the direction of flow speed. When the direction is decided, the interrogation volume is formed as a substantially elliptic shape.  The major axis of the interrogation volume of an elliptic shape rotates until a mean square spatial gradient of a return signal becomes a minimum value.
