This review examines several typical fibre grating flow sensors. Firstly, it introduces the basic principle of fibre grating sensing, and then describes research and development of flow sensors based on FBG sensing principles at home and abroad in detail, including the temperature response and strain response of fibre gratings. Finally, it looks forward to the development trend of flow sensing technology using fibre gratings.
