FIELD: metering flowrate in large-diameter pipelines. SUBSTANCE: pipeline (its diameter may be as large as 300-400 mm) accommodates electromagnetic speed converter that has case, elongated magnetic core, field coil, and pairs of electrodes arranged lengthwise of case on its opposite sides. Connected to electrodes is multichannel measuring device whose microprocessor unit functions to compute flowrate using formula given in description of invention. EFFECT: improved measurement accuracy due to considering location of media interface level in pipeline. 2 dwg
