Abstract: 1. Method for determining and presenting an optimized arrangement and assembly of a measurement system or measurement site of an industrial process measurement- and/or process control installation, which measurement system serves for the measuring of at least one process variable or process parameter and which method proceeds with the aid of at least one first electronic computer and a second electronic computer connected therewith, which second computer includes a display-, a processor-controlled data processing-, and an input-device, and includes the following steps: a) on the basis of process-specific data, especially such that have an influence on the process parameter measured by the measurement system, that are transmitted from the second computer to and into the first computer, an optimized arrangement of the measurement system is calculated; b) then a schematic drawing is produced presenting the arrangement of the measurement system optimized therefor and such drawing is presented on the display-device of the second computer. 2. Method as claimed in claim 1 for determining and presenting the optimized arrangement and assembly of a radiometric measurement system at a container or pipe, which measurement system serves for measuring at least one characterizing parameter of a medium in the container or pipe and which method proceeds with the aid of the first electronic computer and the second computer connected therewith, and includes the following steps: a) with the aid of container- or pipe-specific data, especially data on the basic form and on position, diameter, wall thickness and/or materials and on a measurement range to be expected, which are transmitted from the second computer to and into the first computer, an optimized arrangement of a least one radiation source and at least one radiation detector of the radiometric measurement system at or on the container or pipe is calculated; b) then the activity of the radiation source or radiation sources best suited for the measuring or measurings is calculated; c) then a schematic drawing presenting the container or the pipe and the arrangement of the radiometric measurement system optimized therefor is produced and presented on the display-device of the second computer. 3. Method as claimed in claim 2, in which additionally a linearizing curve and/or a linearizing table serving for evaluating the measurement parameters measured with the detector or detectors is produced for the special, optimized arrangement of the radiometric measurement system at the container or pipe. 4. Method as claimed in one of the claims 2 or 3, in which, in a following method step, a selection of suited devices or components for a radiometric measurement system corresponding to the optimized arrangement is established and compiled on the first computer with the aid of device-specific data in a database administered from there, and the selection is subsequently transmitted to the second computer and displayed on its display device. 5. Method as claimed in one of the claims 2, 3, or 4, in which an optimized arrangement of a radiometric measurement system for measuring a fill level of the medium contained in the container is determined and presented. 6. Method as claimed in one of the claims 2, 3 or 4, in which an optimized arrangement of a radiometric measurement system for measuring a density of the medium contained in the pipe is determined and presented. 7. Method as claimed in one of the claims 2, 3, or 4, in which an optimized arrangement of a radiometric measurement system for measuring a limit level of the medium contained in the container is determined and presented. 8. Method as claimed in the claims 5 to 7, in which an optimized arrangement of a radiometric measurement system for any combination of measurings of limit level, density and/or fill level of the medium is determined and presented. 9. Method as claimed in one of the claims 2 to 8, in which additional accessories for the radiometric measurement system are determined and presented. 10. Method as claimed in one of the claims 2 to 9, in which radiation protection-relevant calculations are performed and presented for at least one radiation protection container for the radiation source or sources. 11. Method as claimed in one of the claims 2 to 10, in which radiation protection-relevant calculations for at least one radiation detector are performed and presented. 12. Method as claimed in one of the claims 2 to 11, in which radiation protection-relevant calculations are performed and presented for an empty container or an empty pipe. 13. Method as claimed in one of the claims 2 to 12, in which the first and the second computers are connected with one another by means of at least one data exchange device and/or over a cable connection. 14. Method as claimed in one of the claims 2 to 13, in which the first and the second computers are connected with one another cablelessly over at least one data exchange device. 15. Method as claimed in one of the claims 2 to 14, in which at least one of the two computers is a stand-alone computer or a work station of a network including other computers. 16. Method as claimed in one of the claims 12 to 15, in which the data exchange device is a modem and/or another adapter for wireless connection with the telephone network. 17. Method as claimed in one of the claims 12 to 16, in which a further determining and presenting of an optimized arrangement and assembly of a radiometric measurement system at a container or pipe is performed on the basis of another radiation source or other radiation sources and/or other detectors and the results are presented on the second computer. 18. Method as claimed in one of the preceding claims 2 to 17, wherein specific data on the first computer present in the form of a database on media are used. 19. Method as claimed in one of the preceding claims 2 to 18, wherein specific data on the first computer present in the form of a database on materials for container- or pipe-walls are used. 20. Method as claimed in the claims 18 and 19, wherein the databases are updated after every determining and presenting of an optimized arrangement of a radiometric measurement system by newly entered data on container, pipe and/or medium. 21. Method as claimed in one of the preceding claims 2 to 20, characterized in that it is part of a more inclusive method for determining and presenting optimized arrangements of measurement systems of an industrial production plant within the framework of a project management. 22. Method as claimed in claim 1 for determining and presenting an optimized arrangement and assembly of at least one pressure measurement system at a container or pipe, which measurement system serves for measuring a pressure and/or a difference pressure.
