Abstract:
A system for blending two-blend components to form a blended final product comprising:a. a first supply line for supplying a first blend component at a first throughput;b. a second supply line for supplying a second blend component at a second throughput, wherein the first supply line and the second supply line intersect to form a blended product line;c. a blended product measuring device positioned in the blended product line for measuring the throughput of the blended product and generating a signal indicative of such throughput;d. an auxiliary measuring device positioned in the first supply line for measuring the throughput of the first blend component, the auxiliary measuring device capable of generating a signal indicative of the first blend component throughput and having a level of accuracy substantially less than that of the blended product measuring device;e. a calculation device for determining the throughput of the second blend component by determining the difference between the throughputs measured by the blended product meter and the auxiliary measuring device and generating a signal indicative of that difference; andf. a blending controller for receiving the auxiliary measuring device signal and the calculation device signal and controlling the blending of the first and second blend components to form a blended product.
