Error Estimation of Ultrasonic Flowmeter Downstream of Elbow

Abstract

A fast breeder nuclear reactor has been investigated to design the compact system and there, a length of an entrance region for a flowmeter may not be kept enough. In order to study the possibility of usage of an ultrasonic flowmeter in such a condition, measurement error and frequency characteristics of the flowmeter located downstream of an elbow were investigated experimentally and numerically. The minimum entrance length and the appropriate measurement plane were discussed.
