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. |
