Abstract
A device for measuring the fill level in a container has an ultrasound sensor and a damping beaker with at least one antechamber. The antechamber has an inlet opening to the container and an outlet opening to the damping beaker, and has a geometric structure, which guides a fluid at least once around the midpoint of the damping beaker. The antechamber has at least two planes lying horizontally over each other. Each plane has a geometric structure, and the geometric structures of the planes are designed so that the fluid streams through the planes in opposite directions. As a result, the path to be traversed in the antechamber is lengthened, and the inflowing medium is additionally swirled. Even foamed media that quickly flow into the antechamber are effectively retained, and degassing is possible prior to entry into the measuring section of the ultrasound sensor.
