Abstract
A calorimetric flow indicator includes a sensor element which forms a temperature-dependent resistance and which heats up in a short period of time by application thereto of electrical current. A resistance variation of the sensor element, induced by cooling, represents a measure of flow velocity of a medium flowing by the sensor element. The sensor element rests against an inner surface of a front wall of a housing projecting into the flowing medium. That section of the housing that includes the front wall and projects into the flowing medium has the shape of an obtusely truncated cone.
