Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A capacitance sensor assembly for determining flow rate comprising: a reservoir including an input passage, at least one retaining wall, wherein the retaining wall includes at least one opening, the opening having an opening size; and a fluid pooling area, wherein the input passage, fluid pooling area, and at least one opening are coupled such that the fluid pooling area can receive fluid from the input passage and fluid can exit the fluid pooling are…
