Abstract
An indicator mounted on a receptacle for determining the proportion of the liquid mixture components in the receptacle of a liquid dispensing apparatus, such as a rug or carpet shampoo device. Even if the receptacle is partly filled with a liquid mixture, the present indicator shows the correct amount to be added to each of the components to thereby fill the receptacle to a given level.
