The EMF-PF Fill Height Measuring Technique Using Multi-Electrodes in Parallel Connection

Abstract:

A new sensor of the electromagnetic flowmeter in partially filled pipes (EMF-PF) is presented. With an array of parallel electrodes constituted by multi-electrodes in parallel connection as the measurement electrodes, the measurement electrodes alternate duties, sensing both the flow velocity and fill height signals. On the sensor pipe bottom, one pair of the electrodes is set as the signal injection electrodes that inject the AC signal used to determine liquid fill height. The theoretical analysis and experiment results indicate it feasible for the EMF-PF to employ this fill height measuring technique .
