Abstract: A flow monitoring device for monitoring mud flow in a return line of a bore hole drilling operation, including a mounting bracket mounted to the return line with a viewing port for access to an interior of the return line. A light source illuminates, through the viewing port, a portion of the mud flow in an observation zone within the return line. A camera creates a plurality of images of the mud flow in the observation zone. A controller is configured to analyze the plurality images to: determine a level of the mud flow in the return line and the presence of at least one irregularity, track a movement of the irregularity across the plurality of images to determine a rate of movement of the irregularity, and calculate a flow rate of the mud flow through the return line based on the movement rate and the determined level.

Abstract: A direct line sampling system includes a flow line for a process flow, a diluent flush line for a diluent, and a sampling valve structure disposed in the flow line. The sampling valve structure includes a sampling chamber and has a first position in which the sampling chamber is in communication with the flow line so as to provide a path for the process flow through the sampling chamber. The sampling chamber captures a sample from the process flow when the sampling valve structure switches to a second position in which the sampling chamber is in communication with the diluent flush line. The diluent flushes the sample to a mixing chamber disposed downstream of the diluent flush line where the sample is diluted. An outlet line extends from an outlet of the mixing chamber to an analysis instrument configured to analyze particles in the diluted sample of the process flow.

Abstract: A port and closure device for a vessel that is configured for use with a glove bag. The port comprising includes a first annular flange with an opening, a second annular flange disposed a predetermined distance from the first flange and also having an opening, and a seal ring disposed adjacent the first annular flange and having an additional opening. At least a portion of the openings are aligned so that a path is provided through the flanges and the seal ring. A slideable door is included in the port between the seal ring and the second annular flange. The slideable door has a first position that obstructs the path and a second position that is outside of the path. Springs are disposed between the first flange and the seal ring that urge the seal ring toward the slideable door. To reduce contamination sites, the springs may be sealed within an annular interface between the first annular flange and the seal ring.

Abstract: A flow cell device for observing a fluid includes a housing defining an inlet and an outlet, a first viewing member, and a second viewing member. The first viewing member, which is disposed in and coupled to the housing, includes a first window and a spray ring. The spray ring includes cleaning ports in fluid communication with a cleaning fluid inlet port. The second viewing member includes a second window and is disposed in and coupled to the housing opposite the first viewing member such that an aperture that is in fluid communication with the inlet and the outlet is defined between the first window and the second window. The spray ring does not extend past a surface of the first window facing the aperture and each of the cleaning ports is oriented such that a fluid provided under pressure to the cleaning ports is ejected toward the second window.
