Abstract
A method for determining a bulk velocity and a mixture speed of sound of a multi-phase fluid flowing in a pipe of a pipeline. The method includes the steps: obtaining a plurality of pressure signals from a plurality of pressure sensors, where each pressure sensor in the plurality of pressure sensors includes a diaphragm for sensing pressure, where the diaphragm of each pressure sensor is aligned with an inner wall of the pipe such that each pressure sensor is flush-mounted on the inner wall of the pipe; determining, using the plurality of pressure signals, a first time-of-flight of one or more flow eddies; determining, using the plurality of pressure signals, a second time-of-flight of one or more sound waves; determining, using the first time-of-flight, the bulk velocity of the multi-phase fluid; and determining, using the bulk velocity and the second time-of-flight, the mixture speed of sound of the multi-phase fluid.
