A disclosed system determines the elevation of an emulsion phase in a vessel. The system includes more than one source-detector pairs connected to the vessel and a computing device. Each of the source-detector pairs include a radioactive source and a radiometric detector, and are positioned at an elevation measured from the bottom of the vessel. The computing device is connected to the source-detector pairs, and is configured to identify the height of an emulsion phase using an upper boundary target density and a lower boundary target density. The height of the emulsion phase is identified by obtaining density readings from at least two of the source-detector pairs, calculating an upper boundary emulsion phase elevation and calculating a lower boundary emulsion phase elevation, each calculation using the density readings, and at least one of the upper boundary target density, and the lower boundary target density.

A disclosed system determines an amount and/or density of material in a container. The system includes a first detector, a second detector, and a processor circuit. The first detector and second detector determine a generally vertical flux of naturally-occurring charged particle entering and exiting the container, respectively. The first and second detectors may include scintillation detectors that detect muons in an energy range of 100-4000 MeV to determine a flux of muons entering the container and exiting the container, respectively. The processor circuit determines a difference in the flux of naturally-occurring charged particles entering the container relative to the flux of charged particles exiting the container. The processor circuit further determines the amount and/or density of material in the container based on the determined flux of charged particles lost by decay in the process materials or vessel walls or deflected from the second detector.
A nuclear level sensing gauge for measuring the level of product in a bin. The gauge includes a source of nuclear radiation positioned adjacent the product in the bin and a housing. A primary scintillator is provided in the housing, adjacent the product in the bin, and opposite the source of nuclear radiation. Nuclear radiation from the source passes through the bin and impinges upon the primary scintillator, generating scintillating light. A light guide conveys the scintillating light from the primary scintillator to light sensing circuitry. The light guide is coupled to the primary scintillator through an air gap. The light guide produces scintillating light flashes in response to absorption of the scintillating light from the primary scintillator. The light sensing circuitry collects the light flashes from the light guide to provide a representation of the level of radiation-absorbing product in the bin.

A nuclear level sensing gauge for measuring the level of product in a bin utilizes a plurality of scintillators (14/16) arranged in a serial fashion. A source of nuclear radiation (S) is positioned adjacent the bin, and the scintillators, which may be bundles of one or more scintillating fibers or scintillating crystals, are positioned in a serial fashion adjacent the bin opposite the source of nuclear radiation, such that nuclear radiation passing through the bin impinges upon the bundles. Light guides (18) carry photons emitted by the scintillators -- which are indicative of radiation passing through the bin -- to a common photomultiplier tube (12). The tube is connected to electronics (10) which convert counts of photons from the PMT into a measure of the level of radiation-absorbing product in the bin.
