A NEW APPROACH TO IMPROVE REPRODUCIBILITY OF ULTRASONIC FLOWMETERS USED IN FULLY DEVELOPED FLOWS

Abstract

Due to its high repeatibility ultrasonic flow meters (UFMs) are ideqm instruments for interlaboratory comparisons. The present paper attempts to improve the performance of UFM for interlaboratory comparisons by estimating weighing factors that reduce the instrinsic errors of this technology. The results have been tested with a DN500 five parallel path time of flight (TOF) UFM at a Bilateral comparison within the PTB. Oustanding results have been accomplished.
