Multi-Parameters Measurement Based on STM32 ARM of Dual-Excited Electromagnetic Flow Meter in Partially Filled Pipes

Abstract

The dual-excited electromagnetic flowmeter with arc-electrodes in the paper can measures liquid level and flow velocity. A pair of electrodes is set as signal injection electrodes on the pipe bottom. AC signal injected used to determine liquid level. The theoretical analysis and experiment results indicate that it is feasible for partially filled pipes.
