It can be understood that, during operation, fluid enters the flow channel 1a from the start end of the flow channel 1a, the fluid rotates under the action of the rotating member 2, and forms a vortex, after the fluid enters the diffusion section of the flow channel 1a, the vortex starts to rotate for the second time, so as to form a gyroscopic vortex precession phenomenon, and the pressure sensing member 4 can know the flow value of the fluid by measuring the secondary rotation precession frequency of the fluid.
Preferably, the hub 21 includes a plurality of ring bodies 211 that are sequentially slidably sleeved along the axial line of the hub 21, a first elastic member 212 is connected between adjacent ring bodies 211, the first elastic member 212 keeps the adjacent ring bodies 211 in a folding trend, an elastic rectifying shell 213 is wrapped on the outer side of the hub 21, the rotor blade 22 is integrally connected with the rectifying shell 213, and a plurality of ribs 214 extending into the rotor blade 22 are arranged on the side portion of the ring body 211. As one example, the first elastic member 212 is an elastic ring.
It can be understood that if the adjacent ring body 211 is unfolded along the axial line of the hub 21, the hub 21 stretches along the axial line thereof, the axial span between the ribs 214 on the adjacent ring body 211 becomes larger, the circumferential span between the ribs 214 on the adjacent ring body 211 is unchanged, and thus, the ribs 214 on the adjacent ring body 211 drive the rotor blade 22 connected with the same to deform, so that the lift angle of the rotor blade 22 becomes larger; conversely, if the adjacent ring bodies 211 are folded along the axial line of the hub 21, and the hub 21 is contracted along the axial line thereof, the axial span between the ribs 214 on the adjacent ring bodies 211 is reduced, the circumferential span between the ribs 214 on the adjacent ring bodies is unchanged, and therefore, the ribs 214 on the adjacent ring bodies 211 drive the connected rotor blade 22 to deform, so that the lift angle of the rotor blade 22 is reduced.

It can be understood that, in operation, if the flow velocity of the fluid in the flow channel 1a becomes large, the acting force of the fluid on the first pressure receiving member 216 also becomes large correspondingly, so that the first pressure receiving member 216 drives the ring 211 except for the start end closest to the flow channel 1a to move towards the end close to the flow channel 1a through the transmission rod 215, so that the hub 21 extends along the axis of itself, and the lift angle of the rotor blade 22 is driven to become large; conversely, if the flow velocity of the fluid in the flow channel 1a becomes smaller, the acting force of the fluid on the first pressure receiving member 216 becomes smaller correspondingly, so that the adjacent ring bodies 211 are closed under the action of the first elastic member 212, and the hub 21 contracts along the axis of itself, thereby driving the lift angle of the rotor blade 22 to become smaller.
Preferably, in order to prevent circumferential rotation between the adjacent ring bodies 211, a guide structure is provided between the adjacent ring bodies 211, and the guide structure includes a first guide groove 211a extending along the axial line of the hub 21, and a first guide portion 2111 slidably connected to the first guide groove 211 a.

As an example, the second elastic member 52 is a spring piece.
It will be appreciated that if the fluid flow rate in the flow channel 1a increases, the lift angle of the swirl vane 22 also increases, so that the vortex core track of the vortex generated after the fluid flows through the swirl element 2 is offset toward the direction approaching the end of the flow channel 1a, and accordingly, the acting force of the fluid on the second pressure receiving element 53 also increases, so that the second pressure receiving element 53 drives the pressure sensing element 4 to displace along the strip-shaped hole 51a toward the direction approaching the end of the flow channel 1a, and the pressure sensing element 4 still aligns with the vortex core track of the vortex, so that the pressure sensing element 4 is always in the optimal detection position.
