The measurement of salt concentration in a plume using a conductivity probe
S. K. Chua, John W. Cleaver, A. Millward · Journal of Hydraulic Research · 1986
Conventional two electrode conductivity probes have a relatively large sensing volume and are therefore inconvenient if measurements are to be made in narrow concentration layers of fluid. A single electrode probe, first discussed by Gibson and Schwarz, has a much smaller sensing volume and the present note discusses some of the practical problems which have been encountered in its use in measuring concentration in narrow layers of fluid adjacent to a solid boundary.
