摘要： A sensing sub-assembly for use with a drilling assembly includes a cylindrical body and at least one sensor coupled to the cylindrical body. The cylindrical body includes an internal flow channel extending therethrough, which is configured to channel a first fluid therethrough and a recessed cavity defined therein, which is configured to receive a continuous stream of a second fluid therethrough. The recessed cavity is coupled in flow communication with an ambient environment exterior of the cylindrical body,and the second fluid flows within the ambient environment. The at least one sensor is configured to determine characteristics of the second fluid in the continuous stream that flows through the recessed cavity.

摘要： A transducer assembly for an offshore drilling riser (15) includes a spool (11) for connecting into the riser (15). A protrusion (31) having upper and lower sloping surfaces extends around the side wall of the spool. A recess extends around the protrusion between the upper and lower sloping surfaces. Upper transducer bores (47) are spaced around the protrusion and extend from the upper sloping surface downward and inward into the spool bore (19). Lower transducer bores (119) are spaced around the protrusion (31) and extend from the lower sloping surface upward and inward into the spool bore (19). A base (51) of a rigid non-metallic material is located in each of the transducer bores (47). A seal ring (65) extends around a cylindrical exterior portion (53a) of each of the bases (51) and one of the transducer bores (47). An acoustic transducer element (71) is mounted to the outer end of each of the bases (51). The transducer assembly can easily detect the parameter of drilling fluid flowing through the spool bore (19) and form a tight sealing.

摘要： A communication method for use by an input/output (I/O) scanner coupled to a programmable logic controller (PLC) includes coupling at least one I/O module to a backplane, and coupling a maintenance module to the backplane. The communication method also includes selectively enabling and disabling communication between the backplane and the at least one I/O module by actuating a switch in the maintenance module such that network communication is maintained by a network interface regardless of whether communication between the backplane and the at least one I/O module is enabled.
