Abstract: An optical sensor may have multiple detection channels to detect different characteristics of a fluid. For example, an optical sensor used in industrial cleaning and sanitizing applications may have multiple detection channels to detect when a system is both clean and properly sanitized. In one example, an optical sensor includes an optical emitter that directs light into a fluid, a first optical detector that detects light transmitted through the fluid, a second optical detector that detects light scattered by the fluid, and a third optical detector that detects fluorescent emissions emitted by the fluid. The optical emitter and optical detectors can be positioned around an optical analysis area. Depending on the application, the optical emitter may be positioned to direct light adjacent a wall of the optical analysis area rather than at a center of the optical analysis area, which may increase the strength of signal on the detection channels.

Abstract: An optical sensor (102) includes a sensor head (112; 304) that has an optical window (312, 314) for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor (102) also includes a flow chamber (110) that includes a housing defining a cavity (356) for receiving the sensor head (112; 304). In some examples, the flow chamber (110) includes an inlet port (352) defining a flow nozzle that is configured to direct fluid entering the flow chamber (110) against the optical window (312, 314) of the sensor head (112; 304). In operation, the force of the incoming fluid impacting the optical window (312, 314) may prevent fouling materials from accumulating on the optical window (312, 314).

Abstract: Embodiments include a flow measuring system for measuring characteristics of a fluid flow. The flow measuring system can include a pair of rotating members rotating synchronously to the fluid flow. At least one rotating member can include a normally-reflecting portion and a non-normally reflecting portion. The normally-reflecting portion reflects an incident beam in a direction parallel to the normal direction of the plane of the normally-reflecting portion. The non-normally reflecting portion reflects the incident beam in a direction non-parallel to the normal direction of the plane of the normally-reflecting portion. The flow measuring system measures the optical characteristics of a beam reflected by the normally-reflecting portion and determines rotational characteristics of the rotating member. The flow measuring system determines characteristics of the flow based on the rotational characteristics of the rotating member.

Abstract: At least one single link of a conveyor chain is configured to support a tension load cell. A main body portion of the link includes a central cavity sized to contain the load cell, which has been inserted therein through an opening of the main body portion, and at least one auxiliary cavity to contain at least one battery cell and circuitry. A cap portion of the link closes off the opening into the cavity to enclose the load cell therein. One or both of the main body and cap portions may include a bore to receive a fastener for attaching to an end of the inserted load cell, and both portions include a bore oriented to receive a pin of a mating dual link of the conveyor chain. The cap portion may also include anti-rotation surfaces to mate with one or both of: the load cell and the opening.

Abstract: Embodiments provide a handheld optical measuring device and method of measuring an optical property of a liquid sample. In some embodiments the optical measuring device includes a handheld controller module having an immersible sensor head and a sampling member including a sample cup and an attachment member that couples the sample cup to the handheld controller module. In some embodiments the attachment member is an elongated rigid member that is hingedly coupled to the controller module, thus providing a folding configuration for enclosing the sensor head with the sample cup during measurements, transportation, and/or storage. In some embodiments the attached sample cup provides a protective shell for the immersible sensor head during use and/or when not in use.

Abstract: Fluid flow meters and methods for measuring different aspects of fluid flow with a non-contact sensor are provided. In some cases a fluid flow gear meter is provided with a fluid chamber that is sealed with a cover portion carrying the non-contact sensor. An optional separation member may be located between the cover portion and the chamber to seal the chamber. In some cases the cover portion and/or separation member are configured to transmit visible light to allow viewing of the fluid chamber, through material selection and/or the presence of viewing cavities within the material. The flow meter is optionally configured to prevent or reduce the transmission of ambient environmental radiation into the flow meter to lessen the likelihood that it may adversely affect an optical non-contact sensor used to detect movement of gears within the chamber.

Abstract: Embodiments provide an optical sensor head and method of making an optical sensor head. In some cases the sensor head can be used as a fluorometric sensor to measure concentrations of substances within a liquid sample of interest. The sensor head includes a light source window and a detector window that transmit light between the sensor head and an analytical area. In some cases the windows include a ball lens positioned within a channel such that the ball lens and the channel create a seal between the interior and exterior of the sensor head.

Abstract: A fluorescence analysis system may include a sensor head that has a light source configured to emit light into a flow of fluid, a detector configured to detect fluorescent emissions from the flow of fluid, and a temperature sensor. The system may also include a flow chamber that includes a housing defining a cavity into which the sensor head can be inserted. In some examples, the housing is configured such that, when a flow of fluid enters the housing, the flow of fluid divides into at least a major stream passing adjacent the light source and the detector and a minor stream passing adjacent the temperature sensor. Such a flow chamber may direct fluid past different sensors components while inhibiting a build-up of solids particles, the generation of air locks, or other flow issues attendant with continuous or semi-continuous online operation.
