Abstract

PURPOSE:To prevent gathering of condensed water inside a pressure conduction pipe and thereby perform accurate measurement of flow rate by a constitution wherein condensed-water returning ports are provided on the upstream and downstream sides of a throttle part separately from differential-pressure take-out ports and communicated with the pressure conduction pipes. CONSTITUTION:The steam flowing through the steam pipe 1 causes differential pressure at the differential-pressure take-out ports 5 and 6 located in the upper- and down-streams of a throttle part 4 as boundary. The steam introduced from the ports 5 and 6 is led into condensers 11 and 12 through ring-shaped connection pipes 7 and 8 and the pressure conduction pipe 9 and 10 respectively and is made to act on a differential-pressure detector 13 by the pressure conduction pipes 14 and 15 through the intermediary of a fixed water head, and, based on the differential pressure detected, the flow rate of the steam is measured. Since the condensed water within the condensers 11 and 12 lowers down to the ring-shaped connection pipes 7 and 8 through the pressure conduction pipes 9 and 10 and is returned into the steam pipe 1 through the condensed-water returning ports 16 and 17, the gathering of the condensed water inside the pressure conduction pipes 9 and 10 can be prevented and an error in measurement can be eliminated.
