Patent number: 10533669Abstract: Methods, systems, and devices are provided for controlling fluid flow in a pressure sensing system. A bi-directional valve can include a first capillary that can couple to a process fluid in a process fluid channel, and a second capillary that can couple to a pressure sensor. The first and second capillaries can include an interface therebetween for controlling fluid flow between the first and second capillaries. The interface region can be configured to allow fluid flow between the first and second capillaries when a magnitude of a pressure difference between the first capillary and the second capillary is less than or equal to a threshold pressure. The interface region can also be configured to prevent fluid flow between the first capillary and the second capillary when the magnitude of the pressure difference between the first capillary and the second capillary exceeds than the threshold pressure.Type: GrantFiled: December 1, 2017Date of Patent: January 14, 2020Assignee: Baker Hughes, a GE Company, LLCInventors: Bjørn Erik Seeberg, Paal Martin Vagle

Patent number: 9400223Abstract: The present invention relates to a retrievable pressure sensor for in situ measurement of pressure in a process fluid in a pipe/chamber. The pressure sensor comprising a pressure-transferring device and an outer sensor part having a pressure sensing element attached at a distance from the pipe/chamber where the pressure is to be measured. The pressure-transferring device comprises a first device for sealing attachment in an opening in a wall of the pipe/chamber where the pressure is to be measured, and has a first separation diaphragm for separating between the process fluid and the pressure-transferring fluid. The pressure-transferring device further comprises a second device for attachment at a distance from the pipe/chamber where the pressure is to be measured. The pressure-transferring device comprises a first cavity with a pressure-transferring fluid, wherein the first cavity comprising a capillary tube for pressure transferring connection between the first device and the second device.Type: GrantFiled: September 7, 2012Date of Patent: July 26, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Paal Martin Vagle, Bjørn Erik Seeberg

Patent number: 9250149Abstract: Retrievable sensor devices and methods are provided that can be easily installed and removed from a sub-sea system without the need to stop the flow of working/process fluid. In particular, a retrievable sensor is provided that can be configured to be located remote from the process fluid to allow for easy access. In other embodiments, an actuator is provided that allows for pressure adjustments to be made during installation and/or removal of the sensor so as to avoid damage to the sensor and/or other system components and to avoid any process fluid/material leakage. Methods are also provided for installing/removing a retrievable sensor, as well as for adjusting a pressure of a retrievable sensor.Type: GrantFiled: June 19, 2013Date of Patent: February 2, 2016Assignee: General Electric CompanyInventors: Bjorn Erik Seeberg, Johan Petersson, Paal Martin Vagle, Christopher Grinde

Patent number: 8122771Abstract: A pressure sensor unit consists of a shaft part adapted to be introduced in an opening through a pipe wall or chamber wall, and a flange part fastened on the outer end of the shaft part for providing sealing around the outer end of the opening. The shaft part inner end reaches in to engagement with a process fluid which pressure is to be measured. The inner end is provided with perforations for admitting process fluid into the inner room of the shaft part. In the inner room and straight behind the inner end it is arranged a block which constitute a base for a separating membrane for transferal of the process fluid pressure via a hydraulic pipe to a pressure sensor element in the flange part. The flange part is constructed as a thin walled pipe, which is enabled because of internal pressure equalization. Thus great savings is achieved by production of the pressure sensor unit.Type: GrantFiled: November 7, 2008Date of Patent: February 28, 2012Assignee: Presens ASInventors: Bjorn Erik Seeberg, Paal Martin Vagle
