Publication number: 20230022527Abstract: A subsea sensor module includes a sensor housing having a first section, a second section and a third section, each section having an outer profile and a module flange having an inner profile. An outer surface of the flange is substantially perpendicular to an outer surface of the housing in the first section. The housing outer profile and flange inner profile are substantially the same along the second section of the housing. A shoulder is formed in the housing outer profile in the third section by a transition of the diameter of the outer profile from a smaller to a larger diameter. The flange has a corresponding shoulder in the flange inner profile; wherein the flange is shrink fit mounted radially outwardly of the sensor housing second section such that the shoulders are in contact.Type: ApplicationFiled: January 5, 2021Publication date: January 26, 2023Applicant: Siemens Energy ASInventors: Hans Knutsson, Andrew Robert Eastoe, Kjetil Haldorsen

Patent number: 10578467Abstract: 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.Type: GrantFiled: April 15, 2016Date of Patent: March 3, 2020Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Andrew Robert Eastoe, Kjetil Haldorsen
