Abstract: A thermal flowmeter includes: a measuring tube; a sensor having a main sensor body and four probes designed to heat the medium, determine the temperature thereof, or influence the flow of the medium in the measuring tube; and an electronic measuring/operating circuit, wherein the probe bodies span a rhombus on the surface of the main sensor body. A first diagonal of the rhombus is parallel to the measuring tube axis, and a second diagonal lies in the measuring tube cross-section. A first probe and a second probe are designed to heat the medium, and at least a third probe is designed to determine the temperature of the medium. The first probe and the second probe are arranged on the first diagonal, and the at least one third probe is arranged on the second diagonal.

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.
