Abstract

A novel multi-electrode electromagnetic flow meter（EMFM） based on weight value theory is developed which uses VM1 microcontroller as the processing core of the converter.The VM1 microcontroller is used to realize control magnetic circuit

acquire voltage signals

data reconstruction

display and regulating control and other functions.By measuring the induced voltages at the boundary of the flow field so as to reconstructs and real time display the velocity distribution.The experimental results demonstrate that this kind of electromagnetic flow meter has high measuring precision and provide reliable velocity reconstruction result.
