Abstract (en)

[origin: WO2018126392A1] 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.
