  • Patent number: 11668618
    Abstract: An apparatus for measuring a pressure of a corrosive or high temperature process liquid includes a pressure sensor in communication with the process liquid via a vertical tube. A buffer gas injected into the vertical tube forms a liquid/gas interface at a desired height. The buffer gas supply is then either isolated or regulated so as to cause the buffer gas pressure within the vertical tube to remain equal with the process liquid pressure. The pressure sensor indirectly measures the process liquid pressure by measuring the buffer gas pressure within the vertical tube, while remaining chemically and thermally protected from the process liquid. In embodiments, pressure measurements from a pair of gas buffered pressure sensors located upstream and downstream of a valve are combined with measurements of the process liquid temperature to determine a flow rate of the process liquid through the valve.

    Abstract: A method of distributing oil to a component within a gas turbine engine includes directing a first oil flow from an oil source to an engine component and back to the oil source, directing a second oil flow from the oil source to a generator driven by the engine and back to the oil source, monitoring a parameter of the second oil flow downstream of the generator and upstream of the oil source, detecting a contaminant in the second oil flow based on the parameter, and reducing the second oil flow to the generator when the contaminant is detected without reducing the first oil flow to the engine component. A shared oil system for a component of a gas turbine engine and a generator driven by the gas turbine engine is also discussed.
