Abstract
Delivery of a chemical sanitizing agent to the rinse system of a warewasher is confirmed by first sensing the absence and subsequently the presence of the sanitizing agent near the outlet of the delivery conduit. Failure to meet these two conditions in this order and within a preset time triggers an alarm to indicate delivery failure.
