[Problem] To provide, for the purpose of measuring large flow rates, a flow sensor that has reduced pressure loss compared to a conventional pressure sensor even if a flow rate increases significantly, is not subjected to a high load, has a rotary blade member for flow rate measurement having a bearing not subjected to abrasive wear, makes accurate flowmeter measurement possible, and has a long product lifetime. [Solution] A flow sensor (10) for measuring the flow rate of a fluid, said flow sensor (10) being provided with a flow sensor pipe body (12) through which the fluid flows, a flow sensor body (24) disposed in the flow sensor pipe body (12) in the direction of the flow of the fluid, and a bypass flow path (62) disposed in the flow sensor pipe body (12) in the direction of the flow of the fluid. |
