| 摘要 |
The invention relates to a device for determining the level of a liquid, at least comprising a radar antenna disposed above the liquid for emitting radar waves to the liquid and receiving radar waves reflected by the surface of the liquid, as well as means for determining the liquid level on the basis of the emitted and reflected radar waves, wherein the radar antenna has an emitting surface which is directed downwards at the liquid and which is horizontally oriented with respect to the surface of the liquid, which emitting surface is provided with means that promote the discharge of condensation that is present on the emitting surface. |
