摘要

In a device for detecting flow of a fluid F, e.g. in a conduit 2, by means of a temperature measuring instrument 4 which comprises at least first and second temperature measuring points P1, P2 and a heating element 20 disposed substantially in the direction of flow of the fluid between the measuring points, the temperature measuring instrument 4 comprises a thermoelement 6 which consists of two wires 8, 10 of different materials, which are conductively connected to one another at a first end 12 and are connected to an evaluation device 18 at their second ends 13,14, whereby the first end 12 of the thermoelement 6 forms the first temperature measuring point P1 and at least one of the second ends 13,14 of the thermoelement forms the second temperature measuring point P2.
