Abstract

Disclosed is a pipe flow rate measurement system comprising: an optical fiber cable disposed to extend along an extension direction of a pipe through which a fluid flows; an irradiation device connected to one end of the optical fiber cable; and an actuator including a propeller disposed in the pipe. As the propeller is rotated by the flow of the fluid in the pipe, a wave is generated in the fluid, and a first vibration detection point of the optical fiber cable is perturbed by the wave. The irradiation device receives an optical signal including an effect caused by the perturbation of the first vibration detection point, and determines at least one of the rotation speed of the propeller, the speed of the fluid at the first vibration detection point, and the flow rate in the pipe at the first vibration detection point, on the basis of the optical signal.
