Abstract: Systems, methods, and software program products for dispensing chemical solutions. A controller receives a signal from a pressure sensor indicative of a pressure of a diluent. The controller determines an expected flow rate of the diluent through an eductor based at least in part on the pressure of the diluent. The controller may further determine an expected concentration of a chemical product in the solution dispensed from a discharge port of the eductor. Based on the expected flow rated and concentration of the chemical product, the controller determines a duration of a dispense stage of a dispensing operation required to dispense a predetermined dose of the chemical product. The controller then causes the diluent to flow through the eductor for the determined duration of the dispense stage. A check valve on the output of the eductor prevents dissimilar chemicals from mixing and reduces a response time of the eductor.

Abstract: Systems, methods, and software program products for detecting an out-of-product condition in a chemical dispensing system. An optical sensor includes a photodetector and a light source configured to generate a beam of light. The light source is positioned such that the beam of light is incident on a supply line at an oblique angle. The supply line displaces the beam of light in dependence on the refractive index of a medium in the supply line. The photodetector is positioned so that it is in the optical path of the displaced beam of light when the refractive index of the of the medium in the supply line is indicative of one of a wet state or a dry state. A detection module receives an electrical signal from the photodetector and determines if the out-of-product conditions exists base thereon.

Abstract: Apparatuses, methods, and software products for analyzing liquids dispensed from a chemical dispensing system. Beams of light having different wavelengths are passed through a liquid dispensed by the dispensing system. The intensity of each beam of light is measured after passing through the liquid. A transmission coefficient is determined by comparing the intensity of the beam of light to a calibration parameter obtained by passing the beam of light through an unadulterated diluent. The transmission coefficients for the beams of light are then compared to corresponding transmission coefficients obtained for one or more known reference solutions to determine one or more characteristics of the liquid being dispensed from the chemical dispensing system.

Abstract: Apparatuses and methods for detecting an out-of-product condition in a chemical dispensing system. An optical sensor includes a photodetector and a light source configured to generate a beam of light. The light source is positioned such that the beam of light is incident on a supply line. A bubble collector is used to form an air pocket from a plurality of bubbles in the supply line generated by an out-of-product state. The supply line displaces the beam of light in dependence on the refractive index of a medium in the supply line, which is altered by the air pocket. The photodetector is positioned so that it is in the optical path of the displaced beam of light when the refractive index of the of the medium in the supply line is indicative of one of a product-available state or the out-of-product state.

Abstract: Systems, methods, and software program products for dispensing chemical products to a washing machine. A dispenser receives a conductivity signal from a conductivity circuit having input terminals coupled to a probe in a tank of the washing machine. The dispenser may compare the conductivity signal to a threshold indicative of a low level of conductivity between input terminals of the conductivity circuit. In response to the conductivity signal breaching the threshold, the dispenser may determine the tank of the washing machine is being drained of a washing solution. In response to the conductivity signal subsequently breaching another threshold indicative of a high level of conductivity between the input terminals, the dispenser may determine the tank is being filled, and dispense a predetermined amount of the chemical product into the tank.

Abstract: A communications network is provided for a water treatment system. A controller is in communication with a plurality of network elements using digital communications. The network elements have a connection configured to connect the network element to the controller or another network element. The controller sends a message to the network elements to configure the network elements for communication with the controller. The controller receives a response from the network elements including a network address and a header. If the network address is a default address, configuration information is sent to the network element for communication on the network. If the network address is not a default address, communication is established with the network element. Messages sent from the controller to a network element having a network address not matching the network address of the network element are sent over the network to a next network element.

Abstract: A system and method for monitoring the levels of product in a chemical dispensing system. A probe assembly is operatively disposed in a container holding product to be dispensed. A detection circuit including an oscillator sensitive to the impendence coupled to the detector is selectively coupled to the probe assembly and produces a signal in response to the impedance of the probe assembly indicating if the level of product in the container has dropped below the probe assembly. The probe assembly includes conductive probes formed from corrosion resistant material infused with carbon and separated by an angle. The level of the first and second conductive probes is adjustable to provide control over the level of product to be detected. Multiple probe assemblies may be selectively coupled to the detection circuit in a repeating sequence by a multi-probe monitoring unit to allow monitoring of multiple containers by a single remote alarm.
