The invention relates to a three-probe procession vortex flowmeter, which comprises a shell, a vortex generator arranged at the front end of the shell, and a despinning device arranged at the rear end of the shell, wherein three piezoelectric sensors are arranged in a middle detection area of the shell; and the three piezoelectric sensors are vertical to a vortex sensing section of a pipeline axis and are fixed on the shell, and are distributed uniformly in 120 degrees mutually based on a central axis of the shell. In the operating state, the three piezoelectric sensors which are distributed uniformly in 120 degrees mutually are adopted to detect fluid vortex procession signals and pipeline vibration and pulsating flow noise signals simultaneously; and according to the fixed-phase relation among three paths of vortex procession signals and the phase relation among the pipeline vibration and pulsating flow noise signals, an output signal is three times of the original signal on one sensor through the processin
