A fluid delivery system includes one or more measure modules for measuring a nd delivering predetermined volumes of one or more different fluids. Each measu re module includes a fluid inlet port, a retention vessel, an overflow aperture to all ow fluid in excess of the desired volume to flow out of the vessel, and an outlet port for dispensing the retained fluid. A calibrating rod adjustably occupies a portion of the volume of the vessel to facilitate precise adjustment of the volume of fluid dispensed by the measure module. In one particular embodiment, a blender includes a plurality of measure modules whose: outputs are coupled together to produce a mixture having a composition defined by the relative capacities of the vessels of the various measure modules. In another particular embodiment, on e blender dilutes a chemical concentrate, and provides the diluted mixture to another blender, which further dilutes the mixture. |
