Patent ID: 8763474

Claim:
A measuring device for measuring physical properties of individual fluids in a multiphase flow flowing through a pipe, wherein the measuring device comprises a measuring section with at least two separate and elongate chambers that are formed by at least one longitudinal barrier, at least one of the chambers comprising means for enabling measurement of the physical properties of the multiphase flow that flows through the chambers, the measuring device is characterized in that the internal diameter of the pipe is smaller at the location in which the measuring section is positioned, in that there is a constriction in the inner pipe wall of the pipe, and wherein the means for measuring the physical properties of the multiphase flow comprise pressure sensors for measuring pressure differences at different locations with different cross-section in the measuring device, and electrodes for measuring electrical properties of the multiphase flow, and wherein at least one inner electrode is provided in connection with the longitudinal barrier and electrically insulated from this barrier, whilst at least one outer counter-electrode is embedded in the inner wall of the pipe and electrically insulated from the inner wall.
