Abstract: Se proporciona un módulo de sensor de presión diferencial co-planar (100). El módulo (100) incluye una base (109) que tiene un par de rebajes ((217), (219)) También se proporciona un par de pedestales ((218), (220)) en donde cada pedestal ((218), (220)) se dispone en un rebaje correspondiente ((217), (219)) y está acoplado a un diafragma aislante correspondiente (222). Un sensor de presión diferencial (208) tiene un diafragma de detección y un par de puertos de detección de presión ((210), (212)). Cada puerto ((210), (212)) del sensor de presión diferencial (208) está acoplado mediante fluido a un diafragma aislante correspondiente (222) por un fluido de llenado. El módulo (100) también incluye circuitos (216) acoplados al sensor de presión diferencial (209) para medir una característica eléctrica del sensor (208) que varía de acuerdo con la presión diferencial. La base (109) está construida de un material que es adecuado para inmersiones en el agua de mar. Un método (300) de construcción de un módulo de sensor de presión diferencial co-planar (100) también se proporciona. En otra modalidad, un módulo de sensor de presión se proporciona. El módulo de sensor de presión (100) incluye una base que tiene un rebaje. Un pedestal está dispuesto en el rebaje y se acopla a un diafragma aislante. Un sensor de presión con un diafragma de detección y un puerto de detección de presión está acoplado mediante fluido al diafragma aislante por un líquido de llenado. Los circuitos están acoplados al sensor de presión para medir una característica eléctrica del sensor que varía con la presión. La base está construida de un material que es adecuado para inmersiones en el agua de mar.

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.

Abstract: A two-wire transmitter senses a pressure using an internal pressure sensor. The transmitter includes an input for receiving a process variable from a remote sensor which is separated from the transmitter. Circuitry in the transmitters transmits information on a two-wire process control loop which is related to the sensed pressure and the process variable.

Abstract: A transmitter with a flame arresting header senses a pressure of a process fluid with a diaphragm which is sealed to the header. The diaphragm transfers the pressure of the process fluid acting an outer surface of the diaphragm to a fill fluid that isolates an inner surface of the diaphragm, and a pressure sensor enclosed in the transmitter senses the pressure of the fill fluid providing an output representative of the pressure of the process fluid. The header includes a chamber on the header's outer face and a passageway extending from the chamber to a tapered opening inside the transmitter with a first portion adjacent to the tapered opening shaped to receive an inlet tube leading to the sensor and a second flame isolating portion open to the chamber. The fill fluid fills the chamber, the passageway, and the inlet tube and is sealed in with a tapered seal pressed into the tapered opening around the inlet tube. The second passageway portion is shaped for flame isolating the tapered seal from the process fluid.
