  • Patent number: 9829475
    Abstract: A sensor including first and second electrodes can be used to determine the concentration of at least one chemical constituent in a fluid sample under test. The electrodes can be disposed in the fluid sample and a predetermined voltage can be applied to a first electrode. The voltage can cause a current to flow between the first and second electrodes through the sample, the current dependent on the concentration of the chemical constituent in the fluid sample. A sense resistor is coupled to the first electrode such that the current flowing between the electrodes flows through the sense resistor. A processor electrically isolated from the electrodes can receive data signals indicative of the voltage drop across the sense resistor and the voltage applied at the first electrode. The received signals can be used to determine the concentration of the constituent in the fluid sample.

  • Patent number: 8527372
    Abstract: Remote monitoring of vehicle washing facilities allows a facility operator to more efficiently manage each site, particularly when combined with environmental conditions that influence the rate at which individual chemicals are used. Accurate chemical exhaustion times can therefore be predicted and communicated to the operator, and wash sequences and parameters may be altered in accordance with such environmental parameters. For example, information related to the composition of soil on a car may be monitored and used to alter the chemicals used in the wash cycle for that car. Other environmental conditions may include without limitation weather conditions, road conditions, types of vehicles, mechanical system status, vehicle temperature, etc.

  • Publication number: 20090283112
    Abstract: A system and method is disclosed for indicating satisfactory times for titrating a chemical solution, e.g., cleaning product, used by a utility device to clean and/or sanitize various types of articles. The utility device is described in an exemplary embodiment as being a warewashing machine that applies the chemical solution to articles provided to the machine on racks. The chemical solution is formed in a solution tank from a combination of at least one chemical product and at least one rinse agent. Whereas the chemical product is described as a detergent, the rinse agent is described as water. Over a time period including multiple wash cycles, the chemical product and the rinse agent are added to the solution tank, thereby changing conductivity of the chemical solution.

  • Patent number: 7516082
    Abstract: A method and system for routing a delivery vehicle to a chemical usage facility is disclosed. The chemical usage facility includes one or more chemical dispense systems that dispense one or more chemical product. The quantity of each chemical product remaining is measured and communicated to a central management facility. The central management facility analyzes a trend in product usage to predict when the product quantity will reach a threshold depletion point. The chemical usage facility is scheduled on the route according to the predicted time associated with the threshold depletion point.

  • Patent number: 7126343
    Abstract: An apparatus and associated process for constructing a conductivity probe are disclosed. The conductivity probe includes at least two magnetic circuits in toroidal shape. Each of these “toroids” includes a ferrite core around which is wrapped a conductive wire (i.e., coil winding). To construct the conductivity probe, a toroid keeper having an upper annulus and a lower annulus separated by a spacer is provided. One of the two toroids is set on the upper annulus and the other toroid is set on the lower annulus. Connection leads extending from the coil wrappings of the toroids are routed from the keeper through wiring channels build into an elongated neck coupled to the keeper. The connection leads terminate at the distal end of the elongated neck relative to the keeper for connection to a controller.

  • Patent number: 6990411
    Abstract: A system and method is disclosed for controlling concentration of a component chemical product in a chemical solution. The chemical solution is formed in a solution tank by combining the component chemical product with water. The component chemical product is dispensed to the solution tank by a chemical dispenser that is controlled by measured conductivity readings of the chemical solution taken in the solution tank. The conductivity readings are analyzed against a conductivity setpoint to determine whether the component chemical product should be added to the chemical solution. A conductivity offset is determined and applied to the analysis thereby taking into consideration any conductivity that may be attributable to constituents of the chemical solution other than the component chemical product. Such constituents include soil washed from the articles and the water used to form the chemical solution.

  • Patent number: 6892143
    Abstract: A system and method is disclosed for controlling chemical dispense operations based on a conductivity offset determined for a chemical solution. The chemical dispense operations are performed by or in conjunction with operation of a utility device, such as a warewashing machine. The chemical solution is formed in a solution tank device by combining water with at least one component chemical product. The conductivity offset, which is the conductivity of the water, is used to normalize the conductivity estimated for the chemical solution relative to the component chemical product in the solution. During various points in time during operation of the utility device, the normalized conductivity is compared to a conductivity setpoint, and if the normalized conductivity falls below the conductivity setpoint, a specified volume of the component chemical product is supplied to the solution tank.

  • Patent number: 6819977
    Abstract: A dispenser for dispensing and a method of dispensing an ingredient for a machine. An ingredient feed mechanism dispenses the ingredient to the machine. A controller is capable of controlling an amount of the ingredient delivered to the machine by varying an amount of time the ingredient feed mechanism is active. The controller has a demand mode which varies the amount of time the ingredient feed mechanism is active as a function of a parameter obtained from the machine. The controller compares the amount of time the ingredient feed mechanism is active with a reference value and switches to a timed mode if the amount of time deviates from the reference value. The controller may have an initial training mode which measures the amount of time the ingredient feed mechanism is active establishes the reference value based upon the amount of time the ingredient feed mechanism is active.
