Abstract
A measurement system is described that includes a flow conditioner for performing the dual functions of conditioning the flow stream and acting as a check meter to the primary meter. Various flow stream characteristics are calculated from the measured differential pressure across the flow conditioner. These calculated values are compared to measurements made by the primary meter for the purpose of identifying performance or accuracy problems in the measurement equipment.
