Effect of Pulsating Flows and Pipe Vibrations on the Performance of a 3" Yewflo Model YF100 Vortwx Flowmeter (Integral Type)
This report describes the effect of pulsating flows and pipe vibrations on the performance of a 3" YEWFLO Model YF100 vortex flowmeter (Integral Type), manufactured by Yokogawa. The instrument was a standard production model manufactured in Japan. The investigation was meant to quantify the effect of pulsating flows and pipe vibrations on the flowmeter performance. The tests were carried out in accordance with a test programme drawn up by TNO and agreed with the WIB and the manufacturer. The applied pulsation and vibration frequencies were within the operating range of the 3" vortex flowmeter; for the Yokogawa vortex (70 Hz and 1025 Hz). All tests were performed with the default settings of the flowmeter for gas applications.
