FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement of flow rate by means of magnetic flowmeters. Magnetic flowmeter (102) for measuring a flow of a process fluid includes flowtube (108), arranged to receive the flow of the process fluid. Coils (222) are arranged adjacent the flowtube. First and second electrodes (224) are arranged to sense an electrical potential of the process fluid, related to an applied magnetic field and a flow rate of the process fluid. Sensed electrical potential is used to calculate the flow rate of the process fluid through flowtube (108).
EFFECT: technical result is indication of variation in the process fluid flow profile and compensation of that variation.
