Abstract: A fluid flow meter is provided that generates a pulsed output to account for viscosity variations. The fluid flow meter includes a controller with a data storage that can store correlations of fluid pressure, volumetric flow rate and pulse frequency for different viscosities, based on a calibration of the fluid flow meter. A pressure sensor can be connected in parallel to a flow chamber of the fluid flow meter for measuring the pressure across the flow chamber.

Abstract: A fluid flow meter is described, that includes intermeshing gears that may rotate synchronously. The fluid flow meter may produce a pulsed output that can be normalized to suitable values according to a method of normalizing input pulses generated in response to the rotation of gears. A volume counter can be incremented by an amount equal to a volume per input pulse each time an input pulse is generated. When the volume counter exceeds a first reference volume, a normalized output pulse can be generated until the volume counter exceeds a second reference volume.

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. The optical sensor may include filters that control the characteristics of light detected by each of the optical detectors.

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, 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: An optical sensor may include multiple 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. In one example, the optical detector can detect scattered and fluoresced light simultaneously. In another example, light is emitted and detected alternatingly. The sensor can be part of a system that includes one or more controllers configured to control the emitting and detecting of light to and from the fluid sample. The controller can use detected light to determine at least one characteristic of the fluid sample.

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: 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.
