Abstract: A co planar differential pressure sensor module (100) is provided. The module (100) includes a base (109) having a pair of recesses (217 219). A pair of pedestals (218 220) is also provided where each pedestal (218 220) is disposed in a respective recess (217 219) and is coupled to a respective isolation diaphragm (222). A differential pressure sensor (208) has a sensing diaphragm and a pair of pressure sensing ports (210 212). Each port (210 212) of the differential pressure sensor (208) is fluidically coupled to a respective isolation diaphragm (222) by a fill fluid. The module (100) also includes circuitry (216) coupled to the differential pressure sensor (209) to measure an electrical characteristic of the sensor (208) that varies with differential pressure. The base (109) is constructed from a material that is suitable for submersion in seawater. A method (300) of constructing a co planar differential pressure sensor module (100) is also provided. In another embodiment a pressure sensor module is provided. The pressure sensor module (100) 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.

Abstract: A remote seal assembly (18 20) for subsea applications is provided. The assembly (18 20) includes an upper housing (34 102) having a fluid coupling (110) for coupling the remote seal to a process fluid pressure measurement device. A lower housing (36 104) is coupled to the upper housing (34 102) and has an interface that is configured to mount to a pressure vessel (12). The lower housing (36 104) also has a process fluid inlet (32). An isolation diaphragm (41 154) is disposed between the upper and lower housings. At least one of the upper housing (34 102) lower housing (36 104) and isolation diaphragm (41 154) are constructed from a material suitable for immersion in saltwater. In some embodiments the lower housing (36 104) has a shoulder (140) disposed about the process fluid inlet (32) and a plurality of self energizing seals (40 42) configured to couple the assembly to a venturi flow meter body (12). A subsea process fluid flow measurement system is also provided that includes a pressure transmitter and at least one subsea remote seal assembly.
