Abstract
An improved system for the monitoring of pH of a liquid containing oil and water by directing the flow of at least a portion of the liquid into contact with the electrode of a pH meter for measuring the pH of the liquid, interrupting the flow of liquid to the electrode periodically, directing the flow of a washing solution into contact with the electrode to remove any depositions on the electrode, and then resuming the flow of the liquid into contact with the electrode to continue the monitoring of pH of the liquid without the need for manual removal and cleaning of the glass electrode.
