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 (-) with inlets adapted for quick connection to one or more liquid inputs and/or liquid outputs of a liquid dispensing system (). A sensor (-) having a data output of liquid flow information for a liquid input to the dispensing system () is operably connected to a controller () to receive the liquid flow information for the liquid input. The controller () 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 () for providing flow information.

Apparatus, method and system for calibrating a liquid dispensing system

A system and associated processes monitor hand hygiene compliance. The system includes hand hygiene product dispensers positioned within areas of concern (AOC) in a facility in which hand hygiene events are to be monitored. The dispensers detect dispense events initiated at the dispenser and transmit a dispense event signal indicative that a dispense event occurred along with dispenser identification information. The system also includes a plurality of compliance badges, each worn by a different person in the facility. Each compliance badge receives dispense event signals corresponding dispenser identification information associated with dispense events initiated by the wearer of the compliance badge. The badges store dispense event records associated with each dispense event initiated by the wearer and thus keep track of all dispense events initiated by the wearer of the compliance badge. One or more data gathering stations positioned at various locations through the facility receive the dispense event information from the individual badges when they come within range. The dispense event information may then be transferred to a local or remote computer for analysis and reporting on hand hygiene events taking place within the facility.

A method of detecting concentration of dipicolinic acid and terbium chloride in a chemical composition with a fluorometer, wherein the fluorometer comprises an excitation source for emitting electromagnetic radiation at one or more wavelengths, and a detector module for detecting fluorescence emitted by dipicolinic acid, emitting electromagnetic radiation from the excitation source at wavelengths that induce fluorescence in dipicolinic acid-terbium chloride combination present in the chemical composition, detecting the fluorescence emitted by the dipicolinic acid-terbium chloride combination via the detector module, and determining the concentration of dipicolinic acid using predetermined relationship between fluorescence emitted and the concentration of dipicolinic acid-terbium chloride combination.

Handheld fluorometer

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.

Fluorescence assay for quantification of picolinate and other compounds in oxidizers and oxidizing compositions

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.

Fluorometer with multiple detection channels

Systems and methods related to a flow meter and/or flow meter operation can include one or more sensors and be capable of detecting parameters of the fluid flowing the flowmeter. One or more sensors can include capacitive sensors having a plurality of electrodes and configured to detect capacitive properties of a fluid flowing through the flow meter. Detected changes in detected properties of the fluid can be evidence of important changes in the fluid, such as an out of product event or a contamination of the fluid.

Gear flow meter with out of product sensor

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.

Multi-channel fluorometric sensor and method of using same

An optical sensor may include a sensor head that has an optical window for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor 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 flow chamber includes an inlet port defining a flow nozzle that is configured to direct fluid entering the flow chamber against the optical window of the sensor head. In operation, the force of the incoming fluid impacting the optical window may prevent fouling materials from accumulating on the optical window.

Self-cleaning optical sensor

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.

Fluid flow meter

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.
