Abstract
A chemical concentration controller and recorder is disclosed for controlling and recording chemical concentrations in a cleaning system. The invention allows a user to control the concentration of two or more chemicals in the cleaning system simultaneously using either concentration-based feed or timed feed. The invention records and archives chemical concentration data from sensors in the cleaning system tanks or the cleaning system fluid conduits during operation of the cleaning system. The data may then be downloaded by a user and analyzed for efficiency and cost control purposes. For example, the data may indicate the overfeeding of chemicals to the cleaning system or leaking valves in the cleaning system.
