Abstract
System for measuring a multiphase flow (109) and the flow velocity comprises: multiple wavelength source (101); multiplexer (103); first fibre optic probe (107) for transmitting optical signals into the multiphase flow and collecting reflected signals; second fibre optic probe (111) for collecting transmitted signals passing through the multiphase flow; optical circulators (105, 113) interconnected with the probes (107,111) for bidirectional transmission of the signals; a filtering device (114) such as a fibre Bragg grating for filtering the signals; wherein the collected reflected and transmitted signals are used to develop an image representation of the multiphase flow data, for example, via an image processing system (125). A reference signal may also be transmitted directly from the multiplexer (103) to the image processing system (125).
