摘要:A novel flow sensor based on fiber Bragg grating is put forward in this paper. Chock parts and elastomers are employed as conversion elements. Two FBGs with the same parameter are installed on elastomers separately. An effective solution Double-grating structure has been taken. The temperature natural compensation and its measuring sensitivity are improved. The sensor can be used to measure the flow of gas and fluid. Its structure and the fluid field around it are simulated and analyzed by ANSYS software within the velocity of 1-20 m / s. The sensitivity of the sensor is simulated and calculated. The performances of the sensor packaging before and after are tested and the reflection spectrum signal characteristic values of the fiber grating are extracted with good linearity, high response sensitivity of 1.71 nm / kg and 0.103 nm / kg, respectively. The experiment results show that the flow sensor owns simple structure, good linearity and high sensitivity.
