Abstract

(Datasheet Available $0) Defines the testing and reporting protocols for flow measurement devices based on the detection of a pressure differential that is created by the device in a flowing stream. This protocol is designed to supply industry with a comparable description of the capabilities of these devices for the measurement of single-phase fluid flow when they are used under similar operating conditions. The objectives of this Testing Protocol are to: 1. Ensure that the user of any differential pressure flow meter knows the performance characteristics of the meter over a range of Reynolds numbers as applicable or defined by tests, 2. Facilitate both the understanding and the introduction of new technologies, 3. Provide a standardized vehicle for validating manufacturer’s performance specifications, 4. Provide information about relative performance characteristics of the primary elements of the differential pressure metering devices under standardized testing protocol
