Abstract
A dispensing system and method for delivering material to a washing device using a capacitance sensor configuration is disclosed. The capacitance sensor configuration allows a controller to monitor and determine a flow rate of fluid exiting a reservoir. The dispensing system uses the flow rate information, along with downstream conductivity information, to control the dispensing of material. Additionally, one or more error conditions are identified during the material delivery cycle based at least partially on the monitored conductivity and capacitance.
