Abstract: A method and system provides for monitoring, troubleshooting and acquiring diagnostics information from an aspirating dispensing system (10). The dispensing system (10) uses an aspirator (12) with a plurality of liquid inlet ports and a flow meter (30) connected in liquid communication with at least one of the liquid inlet ports and a liquid source. The system monitors, troubleshoots and acquires diagnostics information from one or more components of the dispensing system by monitoring operation of the flow meter (30).

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.

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.

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.

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.
