<p>Apparatus (10) is provided for analysing fluid flow in a pipe (24) comprising at least one radiation source (12, 14) to direct radiation through the flow, and at least one radiation detector (12, 14) positioned to receive from the source or sources radiation which has passed through the flow, the source or sources emitting radiation at least at two different energies. The or each detector provides a signal to a processing unit (20) which is arranged to process the signal to provide a series of chronological values, to group the values by magnitude and to analyse the grouped values, for example, to determine phase fraction, type of flow e.g. slug flow, and flow rate.</p> |
