Zusammenfassung:	A method and apparatus are .upsilon.sef.upsilon.! for determining the flo w rate of fluid flowing within a passage. The method comprises the step of m easuring the equilibrium temperature of a location of interest within or pro ximate to the passage within which fluid flows. The temperature of the locat ion of interest is perturbed to a second temperature, and the temperature of the location of interest is then allowed to return to its equilibrium tempe rature. The temperature of the location of interest is monitored as it trans itions between the second temperature and the equilibrium temperature. The m onitored temperature transition is then used to determine the flow rate of t he fluid flowIng within the passage.
