摘要： A pressure sensor is provided. The pressure sensor has a differential pressure sensor adapted to measure differential pressure between two differential pressure sensor inputs in a first differential pressure range. The pressure sensor further includes a first absolute pressure sensor and a second absolute pressure sensor adapted to measure an absolute pressure in an absolute pressure range. The pressured sensor is further provided with a measuring unit configured to determine a differential pressure in a second differential pressure range on the basis of absolute pressure measurements taken by the first and second absolute pressure sensors.

摘要： A subsea flow meter assembly includes a pipe section extending in an axial direction and providing a flow path for a medium. At least four measuring ports are provided at different locations in the pipe section. A first assembly measures at least a differential pressure between a first and second ports and an absolute pressure at one of the ports. A second assembly measures a differential pressure between a third and a fourth ports, and an absolute pressure at one of the ports. A first measuring unit is used to take measurements of the differential pressure and the absolute pressure via the first sensor assembly. A second measuring unit is used to take measurements of the differential pressure and the absolute pressure via the second sensor assembly. An evaluation unit of each determines a flow rate of a flow of medium through the pipe section based on the measurements.

摘要： A subsea assembly includes a housing having a flange interface for interfacing with a flange of a process fluid carrying component, wherein the housing is configured such that boltheads or nuts exerting a fastening force on the subsea assembly when mounted to the process fluid carrying component are spaced from the flange interface so that the dimensions of the housing of the subsea assembly at the flange interface are not affected by a space required for a bolthead or nut fastening tool.

摘要： A method of manufacturing a differential pressure sensor is provided. The method includes providing a housing of a differential pressure sensor and a cover. The cover is mounted to the housing so as to form a pressure chamber. The differential pressure sensor is configured such that in operation, a pressure to be measured is transmitted into the pressure chamber. The method further includes heating a sleeve, placing the heated sleeve around the cover and the housing and allowing the sleeve to cool.
