Multiphase flow measurements have widespread industrial applications in the petrochemical industry.  Most methods are costly and require invasive mounting of a device in the pipeline.  Invasive multiphase flow meters are costly to install due to the shutdown of production of material flowing through the pipe.  A technique outlined in US patent 10,578,471 B2 utilizes a passive acoustic device that measures sound propagation with and against the flow of the material in the pipeline.  This information then reveals the flow of the fluid and the speed of sound of the fluid.  The speed of sound provides phase information.  The described device is passive and mounts externally to the pipeline, hence not interrupting the production of material through the pipeline.  Results of a first attempt at field device are presented and discussed.
