Abstract: A remote seal assembly for subsea applications is provided. The assembly includes an upper housing having a fluid coupling for coupling the remote seal to a process fluid pressure measurement device. A lower housing is coupled to the upper housing and has an interface that is configured to mount to a pressure vessel. The lower housing also has a process fluid inlet. An isolation diaphragm is disposed between the upper and lower housings. At least one of the upper housing, lower housing and isolation diaphragm are constructed from a material suitable for immersion in saltwater. In some embodiments, the lower housing has a shoulder disposed about the process fluid inlet and a plurality of self-energizing seals configured to couple the assembly to a venturi flow meter body. A subsea process fluid flow measurement system is also provided that includes a pressure transmitter and at least one subsea remote seal assembly.

Abstract: A co-planar differential pressure sensor module is provided. The module includes a base having a pair of recesses. A pair of pedestals is also provided where each pedestal is disposed in a respective recess and is coupled to a respective isolation diaphragm. A differential pressure sensor has a sensing diaphragm and a pair of pressure sensing ports. Each port of the differential pressure sensor is fluidically coupled to a respective isolation diaphragm by a fill fluid. The module also includes circuitry coupled to the differential pressure sensor to measure an electrical characteristic of the sensor that varies with differential pressure. The base is constructed from a material that is suitable for submersion in seawater. A method of constructing a co-planar differential pressure sensor module is also provided. In another embodiment, a pressure sensor module is provided. The pressure sensor module includes a base having a recess. A pedestal is disposed in the recess and is coupled to an isolation diaphragm. A pressure sensor having a sensing diaphragm and a pressure sensing port is fluidically coupled to the isolation diaphragm by a fill fluid. Circuitry is coupled to the pressure sensor to measure an electrical characteristic of the sensor that varies with pressure. The base is constructed from a material that is suitable for submersion in seawater.
