Novel precession vortex flowmeter device

The utility model relates to the technical field of vortex flow meters, and discloses a novel precession vortex flow meter device. The display is arranged to display a detection result, the temperature and flow velocity pressure of gas vortex can be detected through the temperature and pressure integrated sensor, and the vortex eliminating vane is arranged to eliminate the vortex. The output end of a motor in the dust filtering mechanism is started to drive a first rotating shaft to rotate before gas enters a flow meter pipe body from an air inlet, the first rotating shaft rotates to drive a rotating disc to rotate, the rotating disc rotates to drive a clamping block to make sliding contact with the inner wall of an arc-shaped frame to abut against the arc-shaped frame to move up and down, and a brush at the other end of a third long plate conducts reciprocating brushing on the surface of a filter screen; the dust collecting box is detached to dump the dust by inwards extruding a spring through a concave bloc
