。[Claims for Utility Model Registration] 1. A system comprising 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, A flow rate sensor in which a guide vane for causing a fluid to make an axial swirling motion 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 axial length of the blades of the impeller is shorter than the axial length of the boss part of the impeller, and the guide blade side is fixed to the boss part, and the permanent magnet of the detector is attached to the boss part without the blades. A flow rate sensor characterized in that a magnetic sensor is attached to the main body in proximity to the permanent magnet. 2. The flow rate sensor according to claim 1, wherein the permanent magnet is provided with auxiliary blades having a smaller radial length than the blades of the impeller.
