Automatic calibration of chemical product dispense systems

摘要

Automatic calibration of dispense parameters of a product dispense system is accomplished via electronic communication of product information. A chemical product includes an electronically readable tag or label that stores and communicates chemical product data concerning the chemical product to a chemical product dispenser. The chemical product data may include, for example, the name of the chemical product, the type or class of the chemical product, manufacturing information regarding the chemical product (e.g., manufacturing date, location, serial number, lot number, etc.), concentration of active ingredient(s), weight, volume, viscosity, density, hardness, specific gravity, shape, color, and/or other data concerning the chemical product. A controller within the dispenser automatically calibrates the dispense parameters based on the chemical product data.

主权项

1. A method comprising:
receiving, with a controller of a chemical product dispenser in which is loaded a chemical product to be dispensed, chemical product data from an electronically readable label associated with the chemical product, wherein the chemical product data includes a chemical product identifier and a current amount corresponding to an amount of the chemical product remaining in the dispenser; automatically calibrating, with the controller, dispensing parameters based on the chemical product data, wherein the dispensing parameters include a dispensing parameter indicative of an amount of the chemical product to be dispensed and a dispensing parameter indicative of an amount of a diluent to be dispensed; dispensing, with the chemical product dispenser, the chemical product and the diluent during a dispensing cycle based on the automatically calibrated dispensing parameters; determining, with the controller, the current amount of the chemical product remaining in the dispenser after completion of the dispensing cycle; determining, with the controller, an actual amount of the chemical product dispensed during the dispensing cycle; updating, with the controller, the chemical product data stored on the electronically readable label, including the actual amount of the chemical product dispensed during the dispensing cycle and the current amount of chemical product remaining in the dispenser after completion of the dispensing cycle; and automatically updating, with the controller and after at least one dispensing cycle, the dispensing parameter indicative of the amount of the chemical product to be dispensed and the dispensing parameter indicative of the amount of diluent to be dispensed based on the current amount of chemical product remaining in the dispenser.
