摘要： A technique facilitates monitoring of a multiphase fluid flow. The fluid flow is directed through a choke valve (22) comprising a choke actuation system (60) which controls a flow rate of the fluid passing through the choke valve. The choke valve also comprises a velocity reduction area which is created by a choke gallery (46). The choke gallery reduces the velocity of the fluid flow to encourage separation of phases of the multiphase fluid (28). A sensor (72) is positioned along the gallery at a desired region to monitor a property of at least one separated phase of the multiphase fluid. For example, the sensor may be positioned proximate a bottom (52) of the choke gallery to monitor a property related to a water phase which separates and transitions to the bottom due to its greater density.
