Abstract: Disclosed is a thermal flowmeter for measuring mass flow of a medium in a measuring tube, comprising: a measuring tube having a tube wall and a tube axis; a sensor with four probes, extending from a sensor base into the measuring tube, wherein the probes are adapted to heat medium, to determine its temperature or to influence a flow of the medium; and an electronic circuit, adapted to operate the probes and to create and to provide flow measured values. Each probe has a probe base and a probe active portion, wherein the probe active portion is adapted to heat the medium, to determine the temperature of the medium, and/or to influence a flow of the medium. The probe bases define a rhombus on a surface of the sensor base, wherein the rhombus is defined by geometric centers of cross sections of the probe bases.

Abstract: The application discloses a thermal, flow measuring device comprising: a sensor including a metal sensor housing having a hollow body and a base; and at least first and second pin sleeves protruding from the base. In a first of the two pin sleeves a first heater is provided and in a second of the two pin sleeves a temperature sensor is provided for ascertaining a temperature of a medium. At least two elongated elements extend with at least the same length as the pin sleeves starting from the hollow body in parallel with the two pin sleeves. On a cutting plane perpendicular to the sensor axis another axis extends that is perpendicular to the connecting axis and wherein the separation of the elongated elements in their course parallel with the axis lessens in certain regions.
