1. A dishwashing system comprising:
- a. means to define a plurality of zones including a prewash zone, a wash zone and a rinse zone;
b. means to introduce heated water into the rinse zone;
c. means to introduce heated water into the wash zone;
d. first measuring means in communication with the means to introduce the heated water into the rinse zone to determine the cost of the water so introduced and to provide a first liquid volumetric output of said cost;
e. second measuring means in communication with the means to introduce the heated water into the wash zone to determine the cost of the water so introduced and to provide a second liquid volumetric output of said cost, the basis of the output of the second measuring means being identical with the basis of the output of the first measuring means; and
,f. means to combine the first and second liquid volumetric outputs and to reflect visually the total cost in a common scale.

Abstract
A cost monitoring system for a dishwashing operation is disclosed. The pumps and/or valves through which the water flows in a dishwashing operation are monitored. Monitoring devices provide outputs on identical cost basis. These outputs are combined and a visual display provided of the cost attendant to the dishwashing operation.

8. A method for monitoring the amount of costs attendant with a dishwashing operation where there is at least a wash step and a rinse step wherein articles to be cleaned are sequentially washed and rinsed in a wash zone and a rinse zone respectively, and pumps and valves provide for the movement of liquids through nozzles to effect the washing and rinsing of the articles, which method includes:
-
placing articles to be cleaned in a wash zone; introducing water and chemicals into the wash zone; contacting the articles to be cleaned with the water and chemicals; measuring the cost of water and chemicals used to clean the articles; providing a first liquid volumetric output corresponding to the cost of said water and chemicals; transporting the articles from the wash zone to the rinse zone; providing rinse water at a predetermined temperature to rinse said articles; contacting the articles to be rinsed with the rinse water; providing a second liquid volumetric output corresponding to the cost of the water used to rinse the articles, the basis of the cost of the water used in the rinse zone being identical to the basis of the cost of the water and chemicals used in the wash zone; combining the first and second liquid volumetric outputs in a common receptacle; and displaying visually the combined volume to reflect the total cost. - View Dependent Claims (9)
