Abstract
Devices and methods for enabling measurement of a selected fluid characteristic in fluid flowing through a conduit. The device includes a body connected in the conduit having an accelerator section and a flow conditioner section within which a measuring unit such as an averaging pitot is maintained. The flow conditioner section includes a straight, substantially constant diameter conduit length selected to provide a settling distance after the accelerator section and in advance of the measuring unit sufficient to provide stabilization and linearization of the flowing fluid prior to measurement. Utilizing the device, repeatable and accurate measurement of the characteristic (flow rate for example) may be conducted over an operating range characterized by up to at least about a 25 to 1 turndown in flow with a constant flow coefficient independent of fluid flow velocity or Reynolds number.
