Abstract
A system for monitoring and controlling the state of a thermal process. The system applies a modulated heat input to a liquid in a vessel and a thermal response measured at the bottom of the vessel provides information for real time processing of thermal properties of the liquid as it is being heated. Detection and control of an unknown boiling point enables a steady simmer or boiling condition in the liquid to be maintained.
