Abstract

An inductive flowmeter with a permanent magnet is disclosed for electrically conductive liquids such as, for instance, sodium, comprising a pair of magnet poles which are disposed diametrically outside a pipe carrying the liquid, and electrodes which are conductively connected to the liquid. Through a new arrangement of the electrodes, not only the measured signal is increased but the dependence of the measured signal on the electric conductivity and the temperature of the liquid, is compensated.
