Beschreibung
Zusammenfassung:	A flow velocity detecting apparatus is provided with: an irradiating device configured to irradiate a fluid passage and a fluid that flows in the fluid passage with measuring light; a light receiving device configured to receive interference light of the measuring light scattered by the flow passage and the measuring light scattered by the fluid; an obtaining device configured to obtain a specified value of information regarding a velocity of the fluid; a determining device configured to determine a usage frequency range of a signal indicating the interference light, on the basis of the specified value; and an outputting device configured to arithmetically operate the usage frequency range of the signal indicating the interference light and to output the information regarding the velocity of the fluid. This makes it possible to set an appropriate arithmetic range and to accurately detect the velocity of the fluid.
