ABSTRACT:
In a system for blending of streams having various flow rates, various concentrations of a selected material, and various transport times from a point where measurements are taken to a mixing tank containing the blended product, signals representative of flow rates and concentrations are continually established for a plurality of streams. These signals are processed in a supervisory computer which provides a calculated control signal to manipulate the concentration of one of the stream being blended in such a manner that a predetermined desired concentration of a selected material is achieved for the blended product.
