Abstract
An apparatus for measuring the bulk density of a fluid within a vessel comprises a radiation source and detector and at least one titanium dip tube penetrating the wall of the vessel to provide a path for radiation from the source to the detector through the vessel via the dip tube. The apparatus facilitates the use of a low energy radiation source for measuring the density of e.g. a gas stream in a thick-walled pressure-resistant vessel.
Claims13
An apparatus for the measurement of the bulk density of a fluid within a vessel comprising a source of radiation located outside the vessel, collimation means to direct the radiation through at least a portion of the vessel, a detector for detecting the radiation, said detector being located outside the vessel and arranged with respect to the radiation source such that it is capable of detecting radiation from said source after it has passed through a portion of the vessel, and at least one dip tube, said dip tube being generally cylindrical and having a dome-shaped closed end, and being arranged to penetrate the wall of the vessel such that the closed end faces the interior of the vessel and being aligned with said radiation source in such a way that radiation from the source may enter the vessel through the closed end of the dip tube.
A method of measuring the bulk density of a fluid within a vessel comprising directing radiation from a radiation source through a portion of a vessel containing the fluid towards a radiation detector and calculating the bulk density of the fluid or a change in the bulk density of the fluid using information about the amount of radiation detected by the detector, characterised in that the radiation source and radiation detector are each located outside the vessel and that the radiation is directed into the vessel via at least one dip tube, being generally cylindrical and having a dome-shaped closed end, said dip tube penetrating the wall of the vessel, being arranged such that the domed end faces the interior of the vessel and being aligned with said radiation source in such a way that radiation from the source may enter the vessel through the closed end of the dip tube.
