Abstract
A static mixer (22) is provided for one or more fluids flowing in a pipe (108), such as oil, water and gas from an oil well. The mixer (22) comprises an element (112, 114) to divide the flowing fluids into at least two streams within the pipe (108) and to deflect two of the resulting streams so that those streams rotate in opposite senses about axes parallel to the direction of flow of the fluid, the element (112, 114) being shaped so as to maintain movement of the flow in a substantially smooth manner. Apparatus (10) is provided for analysing fluid flow in a pipe (108) 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.
