Abstract
A flow conditioner for providing a relatively ideal flow profile when used in a fluid conduit upstream from an orifice meter comprises a bundle of parallel tubes including a central tube having the largest diameter in the range of 0.2 to 0.5 times the conduit internal diameter. The central tube is surrounded by circular arrays of tubes each having a diameter smaller than the central tube so that the flow conditioner produces an orifice discharge coefficient that does not vary from a coefficient created by non swirling, fully developed ideal flow conditions.
