1. A measuring arrangement, comprising:
a sensor unit;
a measuring volume having a wall; and
a mounting system;
wherein the sensor unit is fastened to the measuring volume by the mounting system;
wherein the sensor unit penetrates the wall of the measuring volume, so that the sensor unit is arranged at least partially in the interior of the measuring volume;
wherein the mounting system includes at least one mounting adapter and a coupling ring;
wherein the mounting adapter is fixedly arranged in the wall of the measuring volume;
wherein the sensor unit is movably arranged in the mounting adapter;
wherein the coupling ring is connected to the sensor unit;
wherein the sensor unit is held in the mounting adapter by the connection of the coupling ring to the mounting adapter;
wherein at least one peg element is provided;
wherein at least one recess with a guide contour is provided for receiving and guiding the at least one peg element;
wherein the position of the peg element in the guide contour can be adjusted in or counter to the insertion direction of the sensor unit by at least one rotary movement of the coupling ring and/or by at least one insertion movement of the coupling ring;
wherein the guide contour permits movement of the sensor unit with the coupling ring in axial extension of the sensor unit from a first locking position into a second locking position; and
wherein the sensor unit and the coupling ring are movable together in the axial direction of extension of the sensor unit by pressurization so that the peg element is arranged in the first locking position when pressurization by the medium is present in the measuring volume.
