A novel target type flow sensor has been proposed for liquid flow measurement in pipeline. The force created by the fluid on the target results in the distortion of a cantilever structure. A couple of fiber Bragg gratings (FBGs) are mounted at either side of the cantilever. By monitoring the wavelength shift difference of the two FBGs, the fluid flow-rate can be obtained and the cross-sensitive problem...
A novel electromagnetic force sensor has been proposed. The force created by the input current results in the distortion of a cantilever structure. A couple of fiber Bragg gratings (FBGs) are mounted at either side of the cantilever. By monitoring the wavelength shift difference of the two FBGs, the electromagnetic force can be obtained and the cross-sensitive problem of the FBG sensor can be solved...
