Apparatus and methods are disclosed for acoustically detecting different conditions of boiling occurring within a liquid and developing useful control signals correlated to the detected boiling condition. Distinctions are made between no-boiling, sub-cooled boiling, and full or rolling boiling condi

In combination with a vessel containing a liquid that is expected to boil where the condition of boiling is desired to be known, detection apparatus comprising: (a) transducer means for producing an electric signal correlated to individual random acoustic events occurring within the liquid contained in the vessel; and (b) circuit means for receiving said transducer means signal, identifying groups of acoustic events from bursts of signal activity which correspond directly to individual acoustic event occurrences, determining the rate of group acoustic event occurrence, and classifying said determined rate into one of different output signals, said different output signals being generated by said circuit means in response to different detected degrees of individual random acoustic events occurring in said liquid contained in said vessel.
