Abstract
A method of determining one or more operational parameters of a washing system having a wash tank to which water and material are added. In one embodiment, the method includes monitoring a concentration of material, which is decreased at least partially due to water being added to the wash tank. The method also includes maintaining the concentration of material by dispensing material into the wash tank during a material dispensing operation. Additionally, the method includes generating a parameter indicative of a rate at which the material is dispensed during the material dispensing operation. The method also includes determining a presence of a water flow abnormality based at least partially on the generated parameter.
