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 fluid flow meter is described, that includes intermeshing gears that rotate synchronously. The fluid flow meter has a nominal operating range between a maximum volumetric flow rate and a minimum volumetric flow rate. The flow meter has a flow sensor to produce a pulsed output and a controller operatively coupled to a data storage medium. The controller can receive detection signal from the flow sensor to generate input pulses and determine an input pulse frequency. The controller can determine whether the fluid flow meter is operating outside the nominal operating range and apply a correction function to input pulses to generate linearized output pulses. The controller may generate the correction function based on the input pulse frequency and a predetermined pulse frequency; or based on the time interval between input pulses and a predetermined interval between input pulses; or based on a generic calibration of the fluid flow meter.

Fluid flow meter with linerarization

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 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 is configured to 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 is configured to be connected in parallel to a flow chamber of the fluid flow meter for measuring the pressure across the flow chamber.

The hand-held calibration auditing tool includes a flow meter (-) with inlets adapted for quick connection to one or more liquid inputs to 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.

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.

Conductivity sensor with void correction

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.

Fluid flow meter with linearization

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.

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.
