Abstract: A thermal, flow measuring device for ascertaining a mass flow or a flow velocity of a medium in a pipe. The thermal, flow measuring device has at least one measuring transducer with at least a first and a second sensor element. The first sensor element has a pin-shaped metal sleeve, which has a lowest point on a wall of the metal sleeve in the gravitational direction, wherein there is arranged in the metal sleeve at least one heating means, especially a heatable temperature sensor. The heating means is arranged in the metal sleeve and above the aforementioned point in the gravitational direction, in such a manner that the maximum heat input per unit area from the heating means into the medium occurs in the gravitational direction above the point.
