Электромагнитный метод измерения расхода и уровня жидкости в безнапорных трубопроводах

Abstract

The theoretical study results of magnetohydrodynamic interaction poorly conducting liquid flows in the open canal beds and free-flow pipelines are presented. The volume weight functions for electromagnetic flowmeter depending on the location of electrodes and liquid level are calculated. The possibility of simultaneous measurements of flowrate and level in unfilled pipelines by means of special processing of signals from several pairs of electrodes is shown.
