PCT No. PCT/GB95/02290 Sec. 371 Date Jun. 10, 1997 Sec. 102(e) Date Jun. 10, 1997 PCT Filed Sep. 27, 1995 PCT Pub. No. WO96/10172 PCT Pub. Date Apr. 4, 1996The present invention is an apparatus for analyzing fluid flow in a pipe. The apparatus includes at least one radiation source to direct radiation through the flow and at least one radiation detector positioned to receive from the source or sources radiation which has passed through the flow. The radiation is emitted at least two different energies. Each detector provides a signal to a processing means. The processing means is arranged to process the signal to provide a series of chronological values. The chronological values are grouped by magnitude. The grouped chronological values are then analyzed by the analysis means.
