description The invention relates to a precession flow meter capable of enhancing vortex intensity. The flow meter comprises a flow meter body, a swirler, a spiral guide vane, a rectifier and a piezoelectric sensor, the swirler is mounted on one side, close to the air inlet, in the flow meter body; the spiral guide vanes are mounted on the peripheral side walls of the swirler; the rectifier is installed on the side, close to an air outlet, in the flow meter body, the piezoelectric sensor is arranged in the middle of the upper side of the flow meter body, the bottom end of the piezoelectric sensor extendsinto the flow meter body, the number of the spiral guide vanes is eight, the spiral guide vanes and the swirler are fixed through welding, and the spiral guide vanes are made of stainless steel. The procession flow meter is simple in structure, the rotating strength of fluid in the axial direction of the swirler in the flow meter can be effectively enhanced through the eight spiral flow guide blades, the strength of the v
