Abstract
A system for blending two-blend components to form a blended final product including a first supply line for supplying a first blend component at a first flow rate and a second supply line for supplying a second blend component at a second flow rate. The first supply line and the second supply line intersect to form a blended product line. The system further includes a blended product measuring device positioned in the blended product line for measuring the flow rate of the blended product and an auxiliary measuring device positioned in the first supply line for measuring the flow rate of the first blend component. The auxiliary measuring device may have a degree of accuracy less than that of the blended product meter. Alternatively, the auxiliary measuring device may have the same level of accuracy as that of the blended product meter. A calculation device determines the flow rate of the second blend component by measuring the difference between the flow rates measured by the blended product meter and the auxiliary measuring device. A method for determining the inputs to a blending system for blending a first blend component and a second blend component to form a blended mixture. The method includes measuring the flow rate of the blended mixture directly using a blended mixture flow meter and measuring the flow rate of the first blend component directly using an auxiliary measuring device having substantially less accuracy than that of the blended product flow meter. The flow rate of the second blend component is determined by measuring the difference between the blended mixture flow rate and the first blend component flow rate.
