The invention relates to a method and a device for measuring a level in a receptacle using radar. Via an aerial ( ) directed down into the receptacle, an electromagnetic wave is transmitted and a reflected and time-delayed wave is received, the level being calculated from the time delay. Via one and the same aerial ( ) at least two waves are transmitted and received, which are mutually distinguishable by a detectable characteristic for each wave. The device according to the invention is characterized in that connected to the aerial ( ) is at least one further radar measuring channel ( ), the radar waves of which are mutually distinguishable and distinguishable from the radar wave used in a first radar measuring channel.
