Acoustic method for measuring flow velocity of fluid
An acoustic method for measuring flow velocity of fluid is provided. First, a sound wave is emitted from a transduction surface of a transducer to a fluid. The transduction surface has at least two signal transduction sections. When the sound wave is scattered into a scattered signal by the fluid, the scattered signal is received by the transduction sections. According to the scattered signal, the maximum Doppler frequencies are calculated. Then, according to these maximum Doppler frequencies, the flow velocity of fluid is calculated.
