Abstract
A low product level detector is disclosed which utilizes a sensor comprised of an infrared emitter and receiver to project a beam of light across a cavity/enclosure which contains a solid product. When the product reaches a level at which more solid product should be added, an alarm indicia means is triggered. The alarm indicia means is comprised of an audible horn and a visually perceptible light. The low product alarm is utilized in a dispenser for dispensing a wash chemical solution which has been created by dissolving a solid wash chemical in a diluent. By maintaining a predetermined amount of solid wash chemical in the dispenser, the wash chemical solution maintains a more constant concentration.
