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: A method of fluorometrically detecting the concentration of chemical components in oxidizing formulations is disclosed. In a particular embodiment the detection is of the stabilizing component of picolinic acid (e.g. a compound having the formula indicated below) present in such formulations, although any component which fluoresces may be detected. According to the invention sample preparation of the oxidizing formulation includes adding to said sample an excess of reducing agent to bind peracid, and in the case of picolinic acid, adding to said sample an excess of terbium chloride. The sample then is subjected to radiation to induce fluorescence and the concentration of said chemical component is determined by a linear relationship between fluorescence emitted and the concentration of the target chemical.

Abstract: Systems and methods can be used for correcting for the presence of voids in a fluid when measuring the conductivity thereof. The conductivity of a fluid can be measured using a conductivity sensor. Capacitance electrodes can be used to measure the capacitance of the fluid. The measured capacitance affected by the fluid can be used in combination with the measured conductivity to determine a corrected conductivity value that compensates for possible voids in the fluid. Other parameters, such as the makeup or temperature of the fluid can be used in determining the corrected conductivity measurement. Some such systems include an annular housing and can be inserted or integrated into fluid flow systems so that fluid to be analyzed flows through an aperture defined by the annular housing.

Abstract: Se divulga un metodo de deteccion fluorometrica de la concentracion de componentes quimicos en formulaciones oxidantes. En una forma de realizacion particular, la deteccion es del componente estabilizante de acido picolinico, presente en tales formulaciones, a pesar de que se puede detectar cualquier componente que es fluorescente. De acuerdo con la invencion, la preparacion de muestras de la formulacion oxidante incluye la adicion a dicha muestra de un exceso de agente de reduccion para unirse con peracido y en el caso del acido picolinico, adicion a dicha muestra de un exceso de cloruro de terbio. La muestra se somete luego a radiacion para inducir la fluorescencia y la concentracion de dicho componente quimico por una relacion lineal entre la fluorescencia emitida y la concentracion del producto quimico diana

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.
