247Able can offer numerous configurations of density measurement for both pipeline and vessel configurations to suit your needs. Available with industry standard HART^® protocol for programming and calibration. 

Nuclear density gauges consist of a sealed source in a source holder and a scintillation detector. The source holder is mounted on the side of a pipe or chute with the detector on the opposite side. A focused beam of radiation is transmitted from the source through the pipe and process material to the detector. As the density of the material in the pipe changes the amount of radiation reaching the detector changes. The greater the density of the material, the lower the radiation field at the detector; the lower the density of the material, the higher the radiation field at the detector. 

When the radiation strikes the scintillation crystal, pulses of light are emitted which are detected by the photomultiplier tube. The amount of light is proportional to the amount of radiation striking the detector. The photomultiplier tube then creates a signal that is proportional to the amount of light received which is sent to the electronics for conversion to a 4 to 20mA or other useable process signal. Low density material allows greater radiation to reach the scintillation detector.
