Paper Abstract

A fiber-optic sensor system based on fiber Bragg gratings (FBGs) is proposed and demonstrated to realize water flow measurement with temperature compensation capability. For the FBG cantilever sensor as the key component of the sensor system, a change in the water flow rate gives rise to a monotonic shift in the Bragg wavelength of the grating while the flow direction results in either a redshift or blueshift in the Bragg wavelength due to a stretched or shrunk state of the grating. The resolutions of the sensor system for the forward and backward flow measurement are 58.1 and 166.7 cm3/s, respectively.
