Vortex shedding flowmeter probe

The invention provides a vortex shedding flowmeter probe which comprises a shell and a signal transmission seat installed on the shell, and one end of the signal transmission seat extends into the shell and is provided with an installation cavity; the detection assembly is mounted in the mounting cavity of the signal transmission seat and generates an electric signal in response to the vortex street signal transmitted by the signal transmission seat; and the limiting assembly is mounted in the shell and is used for pre-compressing the detection assembly in the mounting cavity. According to the scheme, the probe and the vortex street empennage are designed in a split mode, the vortex street empennage extends into a medium, the probe is located outside the medium and does not make direct contact with the internal medium, alternating signals generated by periodical falling of vortexes are transmitted to the bottom of the probe through a transmission rod on the empennage, and the problem of acid, alkali and salt
