| 摘要 |
The invention relates to a flow measuring device (1, 21) for determining and/or monitoring a flow of a measurable medium through a measurement pipe (2, 22), comprising at least two temperature sensors (13, 14, 33, 34). A first temperature sensor (14, 34) can be heated and a second temperature sensor (13, 33) is used to set the temperature of the measurable medium. According to the invention, the thermal flow measuring device (1, 21) has at least one sensor (10, 11, 30, 31) for determining the properties of the medium, i.e. the thermal conductivity, the thermal capacity, density and dynamic viscosity or thermal conductivity, temperature conductivity, density and dynamic viscosity. |
