Abstract
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 magne-tometers (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.
