摘要： A combined radiation source holder and beam collimator in which the source holder comprises a rod having a plurality of holes adapted to receive radiation sources and said collimator comprises a tube made of radiation absorbent material and having transmission holes in it, said rod and tube being arranged such that in use each radiation source is aligned with at least one transmission hole aligned to provide a path along which radiation from the source traverses the thickness of the tube to produce a collimated beam of radiation which is projected laterally relative to the rod and tube. The source holder and collimator is suitable for use in a density profiler for measuring a density profile of a medium including at least two liquid and gaseous phases includes an axially distributed source array providing at least 10 collimated ionising radiation beams; an axially distributed radiation detector array, each detector associated in use with one of the beams and producing an output signal in response to incident radiation; and an analyser for the detector output signals to determine the density of the medium traversed by the beams of radiation.

摘要： A nuclear density or level gauge has an elongated transmission chamber adjacent to an elongated source chamber so that they can both be installed through a single nozzle on a high pressure vessel, making an airtight seal with the nozzle. The shape and position of the source chamber allows the positioning of a radiant energy source inside the vessel, a distance from one end of the transmission chamber. The radiation emitted by the radiant energy source travels through contents of the high pressure vessel and then through the elongated transmission chamber to a detector. The method of use of the gauge or multiple gauges, and the adaptation of vessels for such gauges, are also disclosed.

摘要： The invention relates to a method for measuring the level of a medium in a reactor during continuously operated polymerisation processes, whereby the limiting surface of each phase in the reactor is measured with the aid of an ionising radiation. Said method is characterised in that at least one measuring unit, consisting of a radiation source that emits ionising radiation and a corresponding detector, is brought up to the limiting surface in the reactor and is fixed in a flexible manner in the vicinity. To measure the level of the medium, the limiting surface of the phase is determined by measuring the radioactive backscatter of said phase.

摘要： Un système de mesure (14) utilise la rétrodiffusion à neutrons rapides pour mesurer la densité, le niveau et les points de contact des matériaux sensiblement non hydrogénés (18), c'est-à-dire des matériaux autres que ceux contenant de l'hydrogène. On mesure lesdits matériaux (18) dans des cuves (12) à parois épaisses. Le système contient une source de neutrons rapides (16) servant à émettre des neutrons dans le matériau (18) à mesurer. Un système de détection (26) est monté à proximité de la source de neutrons (16), afin de recevoir les neutrons rétrodiffusés. Un système de dégradation d'énergie (22) fait descendre le niveau d'énergie de neutrons rapides jusqu'à une plage de détection souhaitée.

摘要： The invention includes 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 vapour. The method enables the operating parameters of the apparatus to be optimised and provides a means of calculating the % flood of an individual tray.
