Abstract: The invention relates to a method for manufacturing a probe (10) of a thermal, flow measuring device for measuring mass flow of a liquid in a measuring tube, wherein the method comprises steps as follows:introducing a probe core comprising 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; applying a thermoelement to a contact area of the core element or of the solidified hard solder. The invention 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 invention.

Abstract: The present disclosure relates to a method for producing a probe of a thermal flow meter for measuring the mass flow rate of a medium in a measuring tube, the method having the following steps: introducing a probe core in the form of a material to be melted into a first probe casing, the first probe casing having an open first end and a closed second end facing away from the first end; melting the probe core; quenching the probe core to a temperature below the solidification temperature; attaching a thermoelement to a contact surface of the solidified probe core. The invention also relates to a probe obtained according to the production method and to a flow meter including the probes according to the present disclosure.

Abstract: The present disclosure relates to a process connection for connecting a flow measuring device, to a pipeline, the process connection including a base body having an opening for conducting a medium and a flow rectifier, wherein the flow rectifier is inserted into a first recess of the base body and fixed in place by plastic deformation of an edge region of the base body surrounding the first recess, for example, by press fitting.
