Title: Cell for liq. electrical conductivity measurement - using electrode system with two earthed electrodes in tube
Inventor: KROEBEL WERNER PROF DR
IPC: G01N27/07
Filed: 1976-04-17
Abstract: Cell for measuring electrical conductivity of liquids consists of a tube through which the liq. flows. In the walls of this are two circular earthed electrodes. Located symmetrically between those is a single constant potential electrode. The electrodes are embedded in the tube walls to give a smooth cross section. It is also possible for the electrodes to form a frame across the tube. Used esp. in measuring sea water salt content by determination of the conductivity. The problem with cells using a single pair of electrodes is that the signal can vary with ambient conditions and it needs calibration under normal operating conditions because the electric field extends away from the constant voltage electrode. This is avoided in the cell claimed because the second earthed electrode retains the electrical field inside the cell.
