Abstract
A nuclear level sensing gauge for a vesselcomprises a vertical source welland one more level sensing detectorsmounted to vertically spaced nozzles, where the sourcesin the source wellare distributed sources which emit a radiation pattern illuminating a length of greater than one inch of the respective level sensing nozzle, so that thermal expansion or contraction of the vesseldoes not significantly alter radiation illuminating each detectorIn a second embodiment, a vesselincludes plural level sensing nozzles and plurality of level sensing wellseach nozzle and level sensing wellpositioned adjacent to one another such that a source in the well illuminates a detectoron the nozzle. Because the respective level sensing wellsand level sensing nozzles are closely adjacent to one another, thermal expansion or contraction of the vessel does not significantly alter the illumination of the detector
