Abstract: Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.

Abstract: A system and method for performing automated titrations. An automatic titrator utilizes control devices and sensors adapted for various chemical reactions to perform titrations and determine the content of a desired component of a solution. Batch and continuous mode titrations are possible. Titrant is added to a sample either in varying amounts or rates and a titration endpoint is observed via sensors. Control devices detect when the titration endpoint occurs and calculates the desired content. Various reactions within the solution may be suppressed in order to titrate isolated components individually.

Abstract: A dilute chemical solution may be prepared in response to a dispense request by combining multiple concentrated chemicals with a diluent. In one example, a target amount of diluent is dispensed into a container until a measured weight of the diluent reaches a target weight. A first concentrated chemical is also dispensed into the container until a measured weight of the first concentrated chemical reaches a target weight. The liquid solution containing the diluent and the first concentrated chemical is withdrawn from the container and applied on a second concentrated chemical that is a solid state product so as to cause the second concentrated chemical to at least partially dissolve and enter the container. In some applications, the first and second concentrated chemicals react with one another to generate an active molecule in the chemical solution that is not present in either of the two concentrated chemicals.

Abstract: Analytical systems and methods are provided for simultaneously dispensing metered volumes of fluids at different rates and mixing the fluids to generate a mixed sample having the fluids in proportion to the different rates at which they were dispensed. In some cases two or more of the fluids are premixed prior to mixing with other fluids. In some cases a use composition and diluent are simultaneously dispensed at different rates and premixed to form a diluted sample. One or more reagents may be mixed with the diluted sample and the sample mixture can be analyzed to determine characteristics of the use composition.

Abstract: A chemical product dispenser includes one or more timing features. The chemical product may include cleaning, sanitizing, disinfecting, or other chemical products typically dispensed using a conventional spray bottle or other chemical product applicator used in the cleaning industry. The timed dispenser includes a timer and one or more indicators that are activated when one or more predetermined periods of time (such as a contact time or cure time) have elapsed. A timed dispenser audit system further monitors and analyzes use of the timed dispensers throughout one or more facilities, and may generate reports based on the analysis.

Abstract: A dispensing system and methods employed therein uses optical displacement sensing to control dispensation of one or more products. An optical displacement sensor measures displacement of a load beam supporting a vessel from which the product is to be dispensed. The displacement of the load beam is related to the amount (weight) of the product remaining in the vessel. The system may thus control dispensation of the product based on the optical displacement measurements.

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.

Abstract: A solid chemical product is dispensed to prepare a requested amount of a use solution having a requested concentration of the chemical product. In some examples, a target amount of a diluent and a target amount of the chemical product required to prepare the requested use solution are determined. The target amount of the diluent is dispensed into a container. At least some of the diluent in the container is applied to the solid chemical product to create a resultant use solution, which is directed back into the container. The diluent from the container is applied to the chemical product until the amount of the use solution in the container satisfies the requested amount. In some examples, the target amount of the diluent and the target amount of the chemical product are measured by weight.

Abstract: The present disclosure generally relates to a dye that signals when the concentration of a quaternary ammonium compound in antimicrobial solution changes. A sensor is used to monitor changes in the dye wavelength as an indicator of the quat concentration.

The characteristic model provides an estimate of the characteristic of the fluid medium based on a partial least squares analysis of optical transmission measurements through at least one reference fluid medium having a known characteristic.

Abstract: Embodiments provide a handheld fluorometer and method of determining a concentration of a product within a sample. In some cases the handheld fluorometer includes an immersible sensor head that measures a fluorescence of the product and a controller that calculates the concentration of product. In some cases the handheld fluorometer includes a handheld controller module, an immersible sensor head connected to the controller module, a sample cup for containing a water sample, and a fastener that removably fastens the sample cup about the immersible sensor head. In some cases the sensor head is angled with respect to the controller module and the fluorometer provides a substantially stable base. The sample cup can be removed to acquire a sample of water containing the product and then refastened about the sensor head for determining the concentration.
