Advances in Magnetic Flow Metering: A Clamp-on Device

This study presents advancements in a clamp-on flow metering apparatus based on the magnetic flow metering procedure, with a focus on its non-invasive capabilities for the measurement of fluid flow across diverse pipe materials. The proposed metering methodology leverages novel optically pumped magnetometers (OPM), facilitating precise flow detection without disturbing the fluid dynamics of the system. We provide a detailed description of the essential components, including the pre-polarization magnet and the low-field nuclear magnetic resonance (NMR) region for signal preparation. This research repre-sents a pivotal contribution to the ongoing evolution of the magnetic flow metering procedure, advancing its readiness for industrial application.
