Abstract

An apparatus and system for detecting the delivery or nondelivery of a cleaning and sanitizing agent or chemical in automated dishwashers, warewashers, and laundry machines. A detector, comprising a one or more sensors or two or more electrical electrodes are positioned outside the ends of the delivery tube or tubes for the sanitizing agent or chemical. As the sanitizing agent or chemical liquid is released from the delivery tube or tubes, the liquid forms a stream of flow through the air. The flow passes within sensing range of the sensor or sensors, or encompasses the electrical electrodes thereby completing an electrical circuit. When the sensor detects the flow and the sensor is activated, or the circuit completes, a control unit prevents an alarm from sounding. The control unit also causes a flow or spray of water or rinsate to be directed onto the electrical sensors or electrodes, thereby diluting or rinsing any remaining chemical or agent from the conducting surfaces of the sensors or electrodes.
