What does the size of a wire-wound metering rod represent?
The size of a wire-wound metering rod is based on the diameter of wire wound around the rod. The size is usually shown as the actual diameter of wire multiplied by 1000. Thus a size 10 wire-wound rod would be made with wire 0.010 inches in diameter. Smaller size rods have smaller open areas and thus apply less coating than larger size rods. Please be aware that other manufacturers may use an entirely different size designation.
