摘要： A method for determining the position of a liquid interface between a lower tray and an upper tray in a process apparatus such as a distillation column, using gamma scanning and comparing the maximum count rate of gamma photons measured between two trays with the count rate attributed to scanning through the apparatus filled with vapor. The method enables the operating parameters of the apparatus to be optimized and provides a manner of calculating the % flood of an individual tray.

摘要： Techniques, systems, and devices are disclosed for non-invasive monitoring and imaging of nuclear fuel inside a nuclear reactor using muon detector arrays. In one aspect, these detector arrays are placed outside the reactor vessel or building for investigating the reactors without access to the cores, therefore the imaging process is non-invasive. In some implementation, these detector arrays measure both muon scattering and absorption to enable imaging and characterizing not only the very high-Z fuel materials, but also other materials in the reactor, thereby obtaining a more complete picture of reactor status. When applied to damaged reactors, the disclosed proposed techniques, systems, and devices, through the process of providing an image, can reveal the presence (or absence) of damage to fuel rod assemblies or puddles of molten fuel at the bottom of the containment vessel, thus providing crucial information to guide decisions about remedial actions.

摘要： A scintillation detector, especially one for a radiometric measuring device for measuring and/or monitoring a measured variable, especially a fill level of a fill substance located in a container, for covering a predeterminable measuring range as flexibly as possible in shape and length. To this end, the scintillation detector comprises two or more scintillators arranged in series relative to one another for converting thereon falling, radioactive radiation into light flashes, whose light propagates in the respective scintillator toward its ends. Arranged between the scintillators are optical coupling elements, which establish light transmitting connections between adjoining pairs of scintillators. Connected at an end of the series is a photoelectric transducer, which converts light occurring in the series into an electrical signal corresponding to a radiation intensity striking the scintillators. According to the invention, at least one of the coupling elements is a mechanically flexible element, which includes a bundle of light conducting fibers, via which transmission of the light between the two scintillators connected with one another via the fibers occurs.

摘要： An apparatus for determining the fill level of a medium in a container, comprising: an emitting unit to be monitored in the container and emits radioactive radiation into the container; a first detector unit receives radioactive radiation and forwards measurement data relative to the fill level of the medium to a control/evaluation unit; a second detector unit which receives the radioactive radiation, respectively the secondary radiation, wherein two interfaces for transmission of measurement data to the control/evaluation unit are associated with the second detector unit. Via the first interface measurement data are transmitted. Via the second interface measurement data are transmitted. The control/evaluation unit based on measurement data transmitted by the first detector unit and the second detector unit corrects the fill level of the medium in the container in such a manner that the influence of gas or vapor in the gas, or vapor, space on the measured fill level is at least approximately compensated.

摘要： A level gauge using microwaves to determine a distance to a surface of a product in a tank, wherein a measurement signal comprises a first frequency sweep, and a second frequency sweep, and a mixer is arranged to mix the measurement signal with an echo signal to form a first IF signal based on the first frequency sweep, and a second IF signal based on the second frequency sweep. Processing circuitry is adapted to sample the first IF signal and the second IF signal, to form a combined sample vector including samples from each tank signal, and to determine the distance based on the combined sample vector.By combining the samples from two (or more) different sweeps, the number of samples and the bandwidth can both be increased, thus maintaining the range L. However, as the samples are obtained from two separate sweeps, the sweep time for each individual sweep does not need to be increased, and the average power consumption can be maintained.

摘要： A radiometric measuring device for measuring a physical, measured variable, especially a fill level or a density, of a fill substance located in a container, and/or for monitoring an exceeding or subceeding of a predetermined limit value for the physical, measured variable, comprising: a radioactive radiator, which, during operation, sends radioactive radiation through the container; and a detector arranged on a side of the container lying opposite the radiator and serving to receive a radiation intensity penetrating through the container, dependent on the physical, measured variable, and to convert such into an electrical output signal. With this measuring device, in an extremely flexibly predeterminable region to be metrologically registered by the detector, a very exact measuring of the radiation intensity can be put into practice. For this, the detector includes a carrier, on which at least one scintillation fiber is wound, which converts radiometric radiation impinging thereon into light flashes, whose light propagates in the respective scintillation fiber toward its ends. The detector further includes at least one array of avalanche photodiodes operated in the Geiger mode, which convert light impinging thereon into an electrical signal, wherein at least one end of each scintillation fiber is connected to avalanche photodiodes of one of the arrays. The detector also has a measuring device electronics connected to the avalanche photodiodes for producing the electrical output signal, based on the electrical signals of the avalanche photodiodes.
