Abstract
A dual function flow measurement apparatus is provided that combines the functionality of an apparatus that measures the speed of sound propagating through a fluid flowing within a pipe, and measures pressures disturbances (e.g. vortical disturbances or eddies) moving with a fluid to determine respective parameters of the flow propagating through a pipe. The apparatus includes a sensing device that includes an array of pressure sensors used to measure the acoustic and convective pressure variations in the flow to determine desired parameters. The measurement apparatus includes a processing unit the processes serially or in parallel the pressure signals provided by the sensing array to provide output signals indicative of a parameter of the fluid flow relating to the velocity of the flow and the speed of sound propagating through the flow, respectively.
