Abstract

The disclosure relates to a radar-based, fill level measurement device for determining a fill level of a fill substance located in a container. The fill level measurement device includes a high frequency unit for producing high frequency signals and for determining fill level based on received high frequency signals. A hollow conductor is provided for transmitting or receiving high frequency signals. The hollow conductor is subdivided into a first portion facing the high frequency unit, and a second portion faceable toward the fill substance, wherein an insulation transparent for the high frequency signals separates the first portion fluidically from the second portion. A first hollow space is connected fluidically with the second portion and the first hollow space is arranged relative to the second portion behind the insulation. Thus condensate formation on the insulation is prevented, so that the functioning of fill level measurement device is not degraded.
