Paper Abstract

Optical-fiber vortex-shedding flowmeter is prospective in its application in the measurement field not only for the merits up from vortex-shedding flowmeter but also those in optical fiber sensor such as flexibility, strong endurance, anti electromagnetic interference capacity and adaptation in the flammable explosive environment. A new optical-fiber vortex-shedding flowmeter based on white-light interference principle is introduced in this paper. Because of only responding on dynamic disturbance, the all-fiber white-light interferometric flowmeter not only holds the high-sensitivity of interferometric sensors, but also overcomes the instability of the traditional interferometric sensors, which tend to being affected from the external environmental condition such as temperature fluctuation. At last, some experimental curves are presented in this paper.
