Abstract
A sensor base structure (24) for supporting high and low pressure sensors (20,22) having autoclave type connectors (44) and communicating pressurized fluid from the main flowline (10) to the sensors. The sensor base structure comprises a cylindrical manifold (52) having a longitudinal passage (54) therein and including a plurality of lateral bores (58) extending therethrough intersecting the longitudinal passage. One end (60) of each lateral bore threadably receives the autoclave connectors of the respective pressure sensors. The opposite end (61) of the bore (58) threadably receives a plug (62) having an externally threaded portion (64) and a reciprocal autoclave connector (66) facing the pressure sensor to provide a high pressure metal-to-metal seal upon contact with the respective autoclave connectors. Each plug has fluid communication means (70, 72, 74) therethrough such that when the plug is positioned within the lateral bore the reciprocal autoclave connector of the plug is in fluid communication with the longitudinal passage of the manifold. Furthermore, the plug includes a secondary sealing means (76, 78, 80) to provide a seal between the plug and lateral bore of the manifo…
