  • Radiometric fill level measuring arrangement
    Patent number: 8324572
    Abstract: A radiometric measuring arrangement for measuring fill level of a fill substance in a container includes: arranged one above the other in measurement operation on a first side of the container, two or more radiometric radiators, which, in measurement operation, send radioactive radiation through the container, and which, in measurement operation, are arranged in a measuring position in the interior of the container in a pressure resistant, protective tube protruding laterally into the container; and, arranged on a second side of the container lying opposite to the radiators, at least one detector, which serves to receive radiation intensity penetrating through the container as a function of fill level and to convert such into a fill level dependent, electrical signal. The measuring arrangement permits achievement of a highly linear dependence of total detected radiation intensity on fill level.
