    摘要: The present invention is an apparatus and method for measuring flow rate of materials, for example the flow rate of agricultural products. The apparatus includes an x-ray generator positioned near flowing materials, a converter for converting the x-ray radiation which passes through the flowing materials into visible light, a camera for capturing images of the visible light, and a processor for processing the images to determine the flow rate. The invention may also include an image intensifier to intensify the images before being converted by the camera. The method directs x-rays through flowing material, converts the x-rays to visible light, records the intensity of the visible light and derives the flow rate from the intensity measures.

    摘要: An apparatus for estimating a property of an earth formation and a borehole fluid includes a carrier configured to be disposed in a borehole, and a pulsed neutron measurement assembly including a pulsed neutron source configured to emit neutrons into the borehole and the earth formation, and a gamma ray detector. The apparatus also includes a fluid density measurement assembly including the gamma ray detector and a gamma ray source configured to irradiate a borehole fluid with gamma rays. The gamma ray detector is positioned relative to the gamma ray source to detect both of: gamma rays resulting from neutron interactions and gamma rays emitted from the borehole fluid in response to irradiation from the gamma ray source. The apparatus further includes a processor configured to differentiate a pulsed neutron gamma ray spectrum associated with the interactions from a density gamma ray spectrum.
