Abstract
A turbidity sensor includes a housing having a first side along an exterior surface defining a channel for holding a liquid, the housing also having a second side along an interior surface; a first turbidity sensor having an emitter and a receiver adjacent the channel; and a second turbidity sensor having an emitter and a receiver substantially identical to that of the first turbidity sensor located on the second side of the housing spaced from the channel. The liquid is precluded from passing between the emitter and the receiver of the second turbidity sensor at any time. The first turbidity sensor outputs a signal combinable with the signal from the second turbidity sensor to determine the turbidity of the liquid while accounting for the temperature of the liquid without determining the temperature of the liquid. Related dishwasher designs include such sensors.
