Abstract
A liquid blending system for providing three grades: (a) a first base grade; (b) a second base grade; and (c) a fixed blend proportion of the two. A blend control lever coupled to a valve is selectively driven by a differential receiving inputs from fluid meters in the base grade lines. Opposed solenoids pull the lever to one extreme or the other for the two base grades.
