Abstract: An optical sensor can include first and second optical emitters configured to emit light into a fluid sample via an optical pathway. Light from the emitters can cause fluorescence from the sample and/or scatter off of the sample. Scattered and fluoresced light can be received by an optical detector in the sensor via the optical pathway, and used to determine at least one characteristic of the fluid sample. A second optical detector can provide reference measurements of the amount of light emitted to the sample. The second optical emitter and second optical detector can be included in an optical emitter assembly removably disposed in the optical pathway of the optical sensor such that the second optical emitter emits light into the optical pathway toward a fluid sample.

Abstract: Systems and methods for determining a flow rate or volume of fluid. The system includes a positive displacement meter including a plurality of non-contact sensors and gears configured to rotate in response to fluid flow through the meter. The gears may include detectable areas that may be sensed by the plurality of non-contact sensors to determine a rotational direction of the gears. The plurality of non-contact sensors may also be configured to generate respective detection signals indicative of a rotation state of the gears. The controller may be configured to receive the detection signals, determine a current rotation state, and increment a rotational count based on the changes in the current rotation state. The controller may use the rotational count to determine a flow rate or volume of fluid.

Abstract: A fluorometer for measuring fluorescence of a sample includes an excitation source for emitting electromagnetic radiation along a first beam path to induce fluorescence in the sample. An excitation filter transmits electromagnetic radiation from the excitation source toward the sample. An excitation filter holder supports the excitation filter and defines an aperture for passage of electromagnetic radiation from the excitation source. The aperture is positioned asymmetrically relative to the first beam path such that the aperture allows an asymmetrical portion of the electromagnetic radiation in the first beam path to pass toward the sample and the excitation filter holder blocks passage of a corresponding asymmetrical portion of the electromagnetic radiation in the first beam path. The blocked passage of the corresponding asymmetrical portion of the electromagnetic radiation in the first beam path reduces the amount of electromagnetic radiation oriented directly from the emitter module to the detector module.

Abstract: An apparatus, method and system providing for calibration and/or control of a liquid dispensing system is disclosed. The hand-held calibration auditing tool includes a flow meter (36-37) with inlets adapted for quick connection to one or more liquid inputs and/or liquid outputs of a liquid dispensing system (10). A sensor (94-95) having a data output of liquid flow information for a liquid input to the dispensing system (10) is operably connected to a controller (12) to receive the liquid flow information for the liquid input. The controller (12) provides a dilution rate and other liquid flow information for a liquid product input to a dispenser. The tool may include any number of flow meters, and may also include a flow meter connected to an outlet of a dispenser (22) for providing flow information.

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.
