Abstract
A flow velocity measurement arrangement () for determining the flow velocity of an electrically conductive liquid in a liquid line, comprising an air bubble injector () for injecting an air bubble into a liquid flow, a first electrical conductivity measurement cell () downstream of the air bubble injector () and upstream of a measurement line (), a second electrical conductivity measurement cell (') downstream of the measurement line (), an evaluation unit () which determines the flow velocity of the liquid in the measurement line () on the basis of the time-related characteristics of the conductivity measurement results of the two measurement cells (′).
