Abstract: A sampling module is for mounting in a pipeline with a multiphase flow meter and for receiving multiphase fluid from the pipeline. The sampling module includes: a separation chamber for receiving and separating a sample volume of fluid from the multiphase fluid, the separation chamber having a vertical extent when in use; a lower valve for opening and closing a lower fluid path between a lower end of the separation chamber and the pipeline; an upper valve for opening and closing an upper fluid path between an upper end of the separation chamber and the pipeline; a lower sensor for measuring fluid properties of the fluid in a lower part of the separation chamber; and an upper sensor for measuring fluid properties of the fluid in an upper part of the separation chamber.

Abstract: A sampling module (4) for mounting in a pipeline (18) with a multiphase flow meter (2) and for receiving multiphase fluid (16) from the pipeline. The sampling module includes: a separation chamber (6) for receiving and separating a sample volume of fluid from the multiphase fluid (16), the separation chamber (6) having a vertical extent when in use; a lower valve (8) for opening and closing a fluid path between a lower end of the separation chamber (6) and the pipeline (18); an upper valve (10) for opening and closing a fluid path between an upper end of the separation chamber (6) and the pipeline (18); a lower sensor (12) for measuring fluid properties of the fluid in a lower part of the separation chamber (6); and an upper sensor (14) for measuring fluid properties of the fluid in an upper part of the separation chamber (6).
