ACOUSTIC FLUID MONITORING SYSTEM

An acoustic fluid monitoring system, as well as a method for monitoring fluid flow within a pipe using the acoustic fluid monitoring system, are provided herein. The system includes a first sensing probe and a second sensing probe that are acoustically coupled to the outer surface of a wall of a pipe through which a fluid is flowing. The first sensing probe operates at a first resonance frequency, and the second sensing probe operates at a second resonance frequency. The first sensing probe and the second sensing probe are configured to record a first acoustic signal and a second acoustic signal, respectively, corresponding to an acoustic wave propagating through the pipe wall. Characteristics of the first acoustic signal and the second acoustic signal, as well as the relationship between the first acoustic signal and the second acoustic signal, relate to one or more properties of the fluid flowing through the pipe.
