Abstract: An insert assembly for fluid management includes an engagement mechanism and a fluid distribution mechanism with a plurality of fluid connectors configured to transmit fluid therethrough, and a sleeve defining an opening. The fluid distribution mechanism is rotatably coupled to the engagement mechanism such that the two are rotatable relative to each other around a longitudinal axis of the engagement mechanism. An elongated tube extends through the sleeve and at least one valve is coupled to the plurality of fluid connectors by a corresponding fluid line. At a distal end of elongated tube, the elongated tube and valve are coupled via an attachment mechanism, which includes at least one receiving region for releasably receiving the valve. The attachment mechanism, elongated tube and valve form a distal assembly, which distal assembly is configured to be inserted into a port and rest at or near a bottom surface of a covered container.

Abstract: An optical chemical level-sensing device includes an elongated tube for insertion into a top opening of a storage container, with a portion extending above the top of the storage container, which couples to a sealed control unit. A float device resides in the elongated tube in the storage container containing a liquid chemical solution, which includes a target surface configured to reflect optical signals. The sealed control unit includes an optical time-of-flight sensor and a lens that serves as a physical barrier between the liquid chemical solution and the optical time-of-flight sensor, while also allowing optical signals to pass through. The optical time-of-flight sensor emits optical signals through the lens toward the target surface of the float device and measures a return time of reflections of the optical signals off of the target surface to determine a level of the liquid chemical solution within the storage container.

Abstract: A fluid dilution control system includes a processor and a plurality of sensors communicatively coupled to the processor. Each of the plurality of sensors is configured to sense a tracer component in a mixed solution of solution and motive fluid, where the tracer component is present in a pre-defined amount in the solution prior to being mixed with the motive fluid in the mixed solution. Each of the plurality of sensors senses a level of the tracer component present in the mixed solution and transmits the sensed information to the processor such that the processor compares the sensed level of each tracer component to a target level of a respective tracer component and causes a rate of dilution of one or more solutions containing the sensed tracer component to be adjusted to reach the target level of the respective tracer component.
