Paper Abstract

The paper presents a new solution of flowmeter to measure the flowing medium velocity using fiber sensing methods. A Mach-Zehnder interferometer is implemented for the detection of vortices [1] [2]. The measurement of flow is based on the vortex frequency detection of a vibrating diaphragm placed in an optimized measuring chamber. The stress of the vibrating diaphragm is measured with use of a Mach-Zehnder (MZ) fiber interferometer whose fiber arms are fixed with the diaphragm. This solution allows for measuring flow of liquids, gases and vapors in the temperature range of -200°C to +550°C and pressures up to 300 bar.
