Abstract
A fiber sensor with simply a section of SMF inserted in a syringe head for steady micro-flow rate measurement has been proposed and experimentally demonstrated. The end face of the SMF and the measured steady micro-flow is formed as an F-P cavity. The length of the formed F-P cavity is easily be modulated by the fluctuation of the steady micro-flow rate. The experimental results show that the highest sensitivities of steady micro-flow rate is 0.020 nm/(μL/min) and obtained by saline water under 10% concentration at the rate of 100 μL/min.
