| 摘要 |
The invention relates to a device for detecting flow of a fluid, having a temperature measuring instrument (4), which comprises at least a first and a second temperature measuring point (P1 and P2), and a heating element (20), which is disposed substantially in the direction of flow of the fluid between the first and the second temperature measuring point (P1 and P2). The special feature of the invention lies in that 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 by their second ends (13, 14) are connected to an evaluation device (18), with the first end (12) of the thermoelement (6) forming the first temperature measuring point (P1) and at least one second end (13) of the thermoelement (6) forming the second temperature measuring point (P2).
