Abstract
A method for determining flow velocities conducts an electromagnetic signal through a fluid flowing in a delivery line and additionally conducts the electromagnetic signal in a spatially delayed manner. A velocity, a velocity profile, and a volumetric fraction of each of the components of the fluid interacting with the electromagnetic wave is determined from a Doppler shift between the original electromagnetic signal and a resulting electromagnetic signal. An apparatus for determining flow velocities is also provided.
