Patent ID: 7057400

Claim:
A fluid conductivity measuring cell adapted to be fitted to a circulation line for said fluid and comprising an insulative material component body, two cylindrical and coaxial electrodes mounted head-to-tail and axially overlapping on the same insulative material component body, one of the two electrodes, referred to as the inner electrode, penetrating partly into the other, at least partly hollow electrode, referred to as the outer electrode, which cell is characterized in that the body comprises a recess by means of which the two electrodes are accommodated in such a manner as to form two cylindrical spaces, one of which is an external space formed between an internal wall of the recess and an external wall of the outer electrode and the other of which is an internal space formed between an external wall of the inner electrode and an internal wall of the electrode, the external space establishing communication between a fluid inlet and a fluid outlet of the cell, each discharging into the recess and being in fluid communication with the internal space that it surrounds, this internal space serving as a conductivity measuring area.
