Abstract:
1. A computer readable medium that is readable by a computer to measure fluid flow characteristics in a pipeline, the computer readable medium comprising a set of instructions that, when executed by the computer, cause the computer to perform the following operations: calculating a density indicative of flowing fluid density responsive to a volumetric flow rate of fluid flowing in a pipeline adjacent a vortex shedding bluff body and a differential pressure flow rate signal for the flowing fluid indicating differential pressure between an upstream surface and at least one downstream surface of the vortex shedding bluff body, the differential pressure flow rate signal formed at least in part through determining a difference between pressure sensed at the upstream surface of the vortex shedding bluff body and pressure sensed at the at least one downstream surface; calculating a mass flow rate indicative of flowing fluid mass flow rate responsive to the volumetric flow rate and the differential pressure flow rate signal; and providing data to a user thereof, the data representing the calculated density indicative of flowing fluid density and the calculated mass flow rate indicative of flowing fluid mass flow rate.
