Abstract
New and improved method and apparatus for the non-invasive detection of the respective segments and segment interfaces, and the non-invasive determination of the respective segment volumes, of a continuous segmented fluid stream flowing in a transparent conduit are disclosed and comprise means to irradiate the conduit and the flowing fluid stream with radiation energy of spectral content predetermined in accordance with the radiation energy absorbance and refraction characteristics of the fluid segments and the fluid segment-conduit interface, means to detect the radiation energy which is transmitted through the segments and conduit and provide signals indicative thereof, and signal processing means operatively associated with the detecting means and operable to process said signals and perform the stated functions in accordance therewith.
