Abstract

1460892 Conductivity cell MALCOM-ELLIS (LIVERPOOL) Ltd 18 Jan 1974 [19 Jan 1973] 2815/73 Heading G1N A conductivity cell comprises six, linearly aligned, spaced electrodes 28-33. The second and third electrodes 29, 30 are connected to a high impedance amplifier 41 to measure the voltages (proportional to resistivity) produced by current between constant current source 42 connected to fourth electrode 31 and earthed first electrode 28. A second constant current source 43 of indentical magnitude a phase to source 42 but of low impedance is connected to fifth electrode 32 and the sixth electrode 33 is earthed. The constant current may be alternating or direct. The annular electrodes may be fixed in an annular container 22 with flow direction as shown, the assembly being inside and attached to the wall W of a fluid containing vessel. In alternative embodiment the electrode may be on the inside of a pipe or in a container for measuring discrete samples. The earthing if both outer electrodes removes the need for insulation between the cell and a liquid bath.
