Using CFD and real-magnetic field of EM probes to improve the accuracy of flow measurements in mixed flow conditions

Abstract

Flow measurement in mixed flow conditions is a challenging task, which can be performed only by few techniques like ultrasonic and electromagnetic. Usually despite the flowmeter’s special design, the systematic uncertainty of flow rate remains high. In order to overcome this issue, additional site-specific calibration procedure for flat EM sensors is presented in this paper. Procedure includes both a hydraulic and magnetic field analysis. Concept of its application in the engineering practice example are presented.
