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 sensor for a thermal flow measuring device, to a thermal flow measuring device, as well as to a method for the manufacture of such a sensor. The sensor includes a sensor thimble, wherein a defined separation of a sensor element from a thimble floor of the sensor thimble is provided by spacers so that a temperature transfer between the sensor and a liquid flowing around the sensor is provided. Thermal contact between the thimble floor and the sensor element is provided by a solder layer.

Abstract: The present disclosure relates to a thermal flowmeter comprising at least one measurement sensor having at least one sensor element for determining a measured value for determining the flow rate of a medium. A measurement transducer determines the flow rate using the determined measured value. A tubular connecting element connects the measurement sensor to the measurement transducer and a protective sleeve is provided, which is mechanically connected to the tubular connecting element. The protective sleeve has a sleeve casing having at least two openings, an inflow opening through which the medium can be delivered to the measurement sensor and an outflow opening through which the medium can flow out of the measurement sensor. The connection between the protective sleeve and the tubular connecting element is a connection which is positively engaged at least in part.
