Abstract: Provided is an apparatus for measuring the flow velocity of a fluid. The apparatus for measuring flow velocity includes a measurement part which measures a sound source generated when a fluid passes through bellows and a calculating part which calculates the flow velocity of the fluid based on the measured sound source. Also, the calculation part of the apparatus for measuring flow velocity includes a detection part which detects the frequency characteristic of the fluid based on the measured sound source and a determination part which determinates the flow velocity of the fluid based on the detected frequency characteristic. [Reference numerals] (110) Measurement part; (120) Calculation part
