ABSTRACT:
The invention relates to a method and arrangement for measuring using magnetic flow measurement, the flow velocity of a liquid, particularly water. In the solution according to the invention, a component that is in the same phase with the magnetic field is measured from the sinusoidal voltage induced in the electrodes. The solution according to the invention can be utilized, for example, in measuring the flow velocity of water flowing in a water pipeline.
