Abstract (en)

[origin: WO2004042326A2] The measuring element (1) for determining a flow rate of a fluid (22) flowing around the measuring element (1) comprises a guide (4) for guiding an electromagnetic wave along the longitudinal extension thereof and comprises at least one electric heating element (5) that is placed adjacent to said guide (4). The guide (4) can be heated by the heating element (5). An electromagnetic wave, which can be launched into the guide (4), can be influenced according to the temperature of the guide (4) that is dependent on the flow rate of the fluid.
