Improved on-line steam flow measurement device and method

摘要

A system and method for determining a steam flow rate through a conduit of a boiling water reactor (BWR) having a first sensor (34) that is configured to generate a pressure signal based on a pressure at an inlet of a venturi (20) within the conduit, and a second sensor (32) that is configured to generate a delta pressure signal based on a pressure differential across the venturi. A processor (36) determines an instantaneous steam flow rate based on the pressure signal and the delta pressure signal.
