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.
