Patent ID: 7325560

Claim:
A material blender system adapted for coupling with an active material source providing an active material flow and for coupling with a diluent material source providing a diluent material flow, and adapted to deliver a controllable flow of a diluted active material mixture to an active-material-consuming process facility, the material blender system comprising: a material flow metering device for dispensing the active material; a mixing device arranged to mix the active material flow with the diluent material flow to form a diluted active material mixture; a monitor arranged to measure concentration of active material in the diluted active material mixture; and a control element arranged to receive a signal correlative of active material concentration from the monitor and to responsively adjust the material flow metering device to control the dispensing rate of the active material, and maintain a predetermined concentration of active material in the diluted active material mixture; wherein at least one of the active material flow and the diluent material flow is provided to the mixing device without passage through a mass flow controller and without passage through a flow restriction element.
