Abstract
A christmas tree assembly for a subsea hydrocarbon extraction facility, the christmas tree assembly includes a fluid pipeline and a sensor assembly comprising a plurality of sensors configured to monitor a plurality of properties relating to hydrocarbon fluid flow through the fluid pipeline. The sensor assembly includes a differential pressure sensor that is disposed at one or more of across a choke, around a bend or restriction in the pipeline or a dedicated flow restrictor integrated within the pipeline, and a bulk density sensor that is disposed in one or more of a blind T, before or after a choke or in an upwards section of the flow pipeline.
