Abstract:
Systems, methods, and apparatuses for detecting components of a multiphasic flow are disclosed. A flowmeter may include a plurality of optical fibers disposed across a fluid flow. The optical fibers may generate backscattering of a portion of a laser beam transmitted along the optical fibers. The backscattering may be produced by a grating formed by zinc dicyanoaurate formed in each of the optical fibers. Heterodyne detection may be used to determine a Brillouin frequency shift that is used to determine strain and temperature measurements at different locations along the optical fibers. Artificial Intelligence uses the strain and temperature measurements to determine a flow regime of the fluid flow and flow rates of components forming the fluid flow.
