Abstract
A process for online measurement of electrical conductivity to control minimum conductivity of fluids, especially rolling oil, which prevents charging and discharging, by controlled addition of conductivity additives. The process measures the time change of conductivity to determine the amount of extremely fine particulate fouling and the degree of impurity of the rolling oil. The process also provides online measurement of the dielectric constant and online measurement of permeability.
