Abstract
A mixture control system for mixing a bactericidal chemical and water in a reservoir in batches. Flow of the water into the reservoir is initiated by a float actuated switch and the duration of the flow is controlled. While the flow is occurring, a dispenser dispenses chemical into the reservoir according to a preset dispensing cycle which is initiated when the water flow is initiated and also terminates therewith.
