1. A sensor system comprising:
a housing having a middle section, a first end section and a second end section, wherein the middle section has a shape of a cylinder shell, wherein the first end section and the second end section are arranged at opposite openings of the middle section, wherein the first and second end sections are each disc-shaped, and wherein the first end section has at least one opening for receiving at least one locking element;
an electronic circuit; and
an ultrasonic distance sensor,
wherein the electronic circuit and the ultrasonic distance sensor are arranged in the housing,
wherein the sensor system is configured to measure a distance between the sensor system and a surface of a material in a container by an echo propagation time of an ultrasonic burst in air,
wherein the at least one opening is arranged on an outer side of the first end section facing away from the material,
wherein the at least one locking element is configured to connect to a fastening element,
wherein the fastening element is arranged in an inner region of the housing, and
wherein the fastening element is adapted to support the electronic circuit and to fasten the electronic circuit to the first end section.
