Abstract
A device for measuring a fill level of liquid in a container includes a measuring tube arranged inside the container and an ultrasonic sensor arranged outside the container such that a portion of the wall of the container is arranged between the measuring tube and the ultrasonic sensor. The ultrasonic sensor therefore has no contact with the liquid located in the container.
