Annotation:
An electromagnetic flowmeter as a measuring device was used by Fabre in 1932 for recording instantaneous blood flow in arteries. Since that time, the electromagnetic method of flow-rate measurement has proven itself in many areas. This method is used for all conductive liquids: water, acids, alkalis, pulp, etc. Typical areas of application are liquids flow-rate measurement, filling, dosing and precise measurement during commercial metering. The production and application of electromagnetic flowmeters with a flow-measuring channel of a circular cross-section prevails in the territory of the Russian Federation. The complexity of manufacturing electromagnetic flowmeters with a flow-measuring channel of a rectangular cross-section lies in determining the optimal geometry of the flow part and its conjugation with a round channel, providing the specified hydraulic losses in the flow measurement range.
