SYSTEMS AND METHODS FOR MONITORING FLUID FLOW IN SHUNT SYSTEMS AND OTHER FLOW-RELATED CONDUITS

摘要

A flow monitoring apparatus includes at least one conduit configured to couple to the flow conduit system, the at least one conduit defining a channel for a fluid flow. A material exhibiting a strain-sensitive Raman scattering signal positioned within the channel, wherein at least a portion of the material is configured to deform when the fluid flows through the channel. A light source is configured to direct light onto the material to generate a spectroscopic signal to detect deformation of the material. The identification of the deformation allows a user to determine a flow rate of the fluid.
