Abstract
A method for audibly detecting a fluid flow state change in a flow meter pipeline. The flow state change may be identified as an upset in the normal flow state. The upset may be corrected to improve the accuracy of the flow meter. A system includes acoustic sensors mounted in the flow meter pipeline, and a computer to collect audible data from the acoustic sensors and compare the audible data to a baseline to detect an upset in the normal fluid flow state.
