Abstract: The present disclosure relates to a method for manufacturing a probe of a thermal, flow measuring device for measuring mass flow of a liquid in a measuring tube, wherein the method includes: introducing a probe core including a hard solder and a core element into a first probe sleeve, wherein the first probe sleeve has an open first end and a closed second end away from the first end; melting the hard solder; affixing the core element by cooling the hard solder to a temperature less than the solidification temperature; and applying a thermoelement to a contact area of the core element or of the solidified hard solder. The present disclosure relates, furthermore, to a probe resulting from the manufacturing process as well as to a flow measuring device having at least one probe of the-present disclosure.

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.

Abstract: A sensor of a thermal flow measuring device, as well as the flow measuring device itself. The sensor comprises a sensor platform, which bears at least one measuring sensor element and a heated sensor element. Each of the at least two sensor elements is surrounded by a metal sleeve, which protrudes from the sensor platform. The sensor has a plate-shaped element, which defines a plane, whose axis extends parallel to the axis of at least one of the metal sleeves, wherein the plane is spaced from the sensor platform in the axial direction of the metal sleeve. The metal sleeve with the heated sensor element has a terminal end face and the plate-shaped element is provided along the end face of the metal sleeve with the heated sensor element for flow guidance.
