Accuracy Improvement of Ultrasonic Flowmeter for Nuclear Power Station; ‘2nd Report’

Influence of Two-dimensional Upstream Pipe Condition, Flowconditioners and Remounting of Transducers

Abstract

An ultrasonic flowmeter has a possibility of replacing flow nozzle and orifice meter as a main feedwater flowmeter in nuclear power stations. This paper describes the examination about the influence of the two-dimensional upstream condition, flowconditioner and remounting of transducers using a cramp-on type ultrasonic flowmeter.
