The present invention comprises method of measuring a parameter of a multiphase flow of a fluid and apparatus therefore. The apparatus comprises a buffer chamber apparatus that is operably fluidly coupled to a pipe bearing a fluid comprised of components of different densities. The buffer chamber apparatus has structure that defines a substantially fluid tight chamber that is in flow communication with the fluid borne in the pipe. One or more ports are defined in the chamber structure whereby the fluid in the chamber may be selectively accessed for sensing a parameter of the fluid. The fluid in the chamber resides in a substantially stable state promoting the separation of the different density components of the fluid.

A process for transporting deaerated bitumen froth in a pipeline is described which comprises injecting water into the pipeline prior to deaerated bitumen froth injection to wet the interior walls of the pipeline. The deaerated bitumen froth is then injected into the pipeline at a critical velocity above 0. 3 m/sec thereby initiating self-lubricating core-annular flow of the bitumen froth.
