DEVICE FOR CHARACTERIZING THE FLOW OF A MULTIPHASE FLUID IN A TUBING

摘要

The invention relates to a device for integrating electrodes characterizing the flow of a multiphase fluid in a tubing. The device includes a tube section made out of an electrically insulating material and bearing the electrodes on its external surface. A metal compensation sheath encircles the section, being separated from the latter by an insulati ng and incompressible fluid. An annular chamber outside the sheath communicates wit h the inside of the tubing. The sheath is fixed on seal rings inserted at the ends of the section, by reinforcement for example.
