Abstract:
1. A system comprising: a container into which a target weight of a diluent required to prepare a requested amount of a use solution is dispensed; a weighing device positioned to obtain container weight information concerning a weight of the container and any contents thereof; and a controller that receives a dispense request specifying the requested amount of the use solution to be prepared and a requested concentration of a chemical product in the use solution, determines the target weight of the diluent required to prepare the requested amount of the use solution, determines a target weight of the chemical product to be dispensed required to prepare the requested amount of the use solution, and manages application of the diluent onto the chemical product until an amount of the use solution in the container satisfies the requested amount based on the container weight information, wherein the controller further initiates a spray on/off cycle including spraying the chemical product with at least some of the diluent from the container for a first predetermined period of time and stops the spraying of the solid chemical product for a second predetermined period of time, receives the container weight information, determines a weight of the use solution in the container from the container weight information, compares the difference between a target weight of the requested use solution and the weight of the use solution in the container with a threshold, and repeats the spray on/off cycle until the threshold is satisfied.
