A method and a device serve for measuring fluidic or calorimetric parameters, for example the velocity of flow, and comprise the steps of heating up a sensor element arranged in a measuring environment, to a temperature higher than the surrounding temperature of the measuring environment, and deriving the parameter from the heat transmission between the measuring environment and the sensor element. In order to permit measurements the result of which is systematically independent of the absolute value of the heating power in the sensor element, two measurements are carried out successively at different temperatures, in the stationary condition. One determines the heating power at both these operating conditions and derives therefrom the parameter to be measured (FIG. 7).
