For this purpose, the measuring system comprises a 3D camera (2) and a radar-based fill-level measuring device (1). The 3D camera (2) is used to first capture at least one 3D image ([pi,j]) of at least one portion of the empty container interior. On the basis of the 3D images ([pi,j]), a data set or a digital spatial model is created which represents the geometry of at least this portion of the empty container interior. In order to create the required three-dimensional surface or fill-level profile (L(a, ꞵ)), the fill-level measuring device (1) is based on a digital beam forming principle, such as the MIMO principle. Therefore, the fill volume in the container (3) can be determined on the basis of the data set reflecting the geometry in the container interior, and on the basis of the fill-level profile (L(a, ꞵ)).
The invention relates to a radioprotective container (11) of a measuring system which is used for radiometric density or fill level measurement (1). In accordance with the invention, the radioprotective container (11) is based on two main bodies (110, 111) which are connected to one another in each case via a planar surface (1101, 1111), for example by means of welding, so that a plane (E) is defined. The radiation hollow conductor (113) for bundled irradiation runs in this plane (E), wherein the radiation hollow conductor (113) is formed by indentations in the main-body surfaces (1101, 1111). In accordance with the invention the radioprotective container (11) comprises radiation absorption structures (114, 114', 114''), which are formed by indentations and complementary elevations in the main-body surfaces (1101, 1111) lying one against the other. An advantageous feature of the two-part design is that steel-based refractory main bodies (110, 111) can be used, wherein the indentations and elevations for the radiation hollow conductors (113) and the radiation absorption structures (114, 114', 114'') respectively can be produced by means of surface machining. In accordance with the invention it is ensured by means of the radiation absorption structures (114, 114', 114'') that no radiation exits laterally from the radioprotective container (11).

The invention relates to an FMCW-based fill-level measuring device (1) of which the fill-level value (L) can be compensated for with regard to component tolerances of clocking components. For this purpose, a diagnostic unit (14) of the fill-level measuring device (1) determines, repeatedly if necessary, a first compensation factor (k1) by comparing the clock rate (clk1) of the signal-generating PLL (11) with the sampling rate (clk2) of the analog-to-digital converter (12). On the basis of the first compensation factor (k1), the determined fill-level value (L) can be compensated for with regard to these sampling or clock rates (clk1, clk2) without it being necessary to use a possibly external high-precision reference source for this purpose. This increases the precision of the fill-level measurement. In addition, the fill-level value (L) is considered to be traceable when the first compensation factor (k1) is determined repeatedly, as a result of which specific safety requirements for the fill-level measuring device (1) can be met.

The invention relates to a measurement device neck (12) of a radar-based fill level measurement device (1) that is used to determine a fill level profile (L(a, ꞵ)) of a filling material (2). In this case, the measurement device neck (12) is distinguished by the fact that the waveguides (121, 121', 122, 122') for making contact with the antenna arrangement (10) are lined up in the interior along a contour (k1, k2) which surrounds the device neck axis (a) in a radially symmetrical manner and adjoins the device neck (12). This is firstly advantageous in terms of the production of the measurement device neck (12) since the waveguides (121, 121', 122, 122') can be produced together as a monolithic base body (123) in order to thus be mounted in the measurement device neck (12) with little effort. The arrangement according to the invention of the waveguides (121, 121', 122, 122') in the measurement device neck (12) also facilitates thermal management in the transmitting/receiving electronics (11) of the fill level measurement device (1) since the thermally critical radar modules (10') thereof can be spaced apart to the maximum extent from one another.
