Claims

[Scope of utility model registration request]

A main body, an impeller rotatably disposed in a flow path formed in the main body, and a detector for detecting the rotation of the impeller, the flow path having an axial swirling motion in the fluid. A flow rate sensor in which a guide vane is non-rotatably attached to the main body adjacent to the upstream side of the impeller, and the vanes of the impeller are substantially parallel to the axis, the vanes are disposed downstream of the impeller. A flow sensor characterized in that a rectifying device having a plurality of rectifying passages substantially parallel to the axis of a vehicle is provided adjacent to an impeller.
