Pelavin, M

In apparatus for the detection of the respective segments, and the respective segment interfaces, of a continuous fluid stream which comprises alternating fluid segments flowing in an optionally transparent conduit, said fluid segments having different radiation energy absorbance and/or refraction characteristics, the improvements comprising, radiation energy source means disposed without said conduit and operable to irradiate the same and said flowing fluid stream, radiation energy detecting means disposed without said conduit and operable to detect the radiation energy from said source means which is transmitted through said conduit and said flowing fluid stream, and to output a signal indicative thereof, and means to process said output signal to indicate said fluid segments and said segment interfaces respectively, wherein, said fluid segments comprise segments of liquids, and wherein the spectral content of said radiation energy is generally outside the radiation energy absorbance range of said liquids.
