A subsea flow meter assembly (100) for measuring the flow of a medium is provided. The subsea flow meter assembly (100) has a pipe section (101) extending in an axial direction and providing a flow path for a medium. At least four measuring ports (11, 12, 13, 14) are provided at different locations in the pipe section (101). A first sensor assembly (20) is configured to measure at least a differential pressure between a first and a second measuring port (11, 12) and an absolute pressure at one of the first and second measuring ports (11, 12). A second sensor assembly (30) is configured to measure at least a differential pressure between a third and a fourth measuring port (13, 14), and an absolute pressure at one of the third and fourth measuring ports (13, 14). A first measuring unit (50) is mounted to the pipe section (101) and configured to take measurements of the differential pressure and the absolute pressure by means of the first sensor assembly (20). A second measuring unit (60) is mounted to the pipe section (101) and configured to take measurements of the differential pressure and the absolute pressure by means of the second sensor assembly (30). An evaluation unit of each measuring unit (50, 60) determines a flow rate of a flow of medium through the pipe section (101) based on the pressure measurements. |
