    Yarn measuring adapter with rubber coated measuring wheel and unique "wrapper" roller for speed and
     length measurement of filaments (max. 0.5 mm ) or thin, flexible wires (max. 0.3 mm ). This precision roller
     directs the filament on to the low-inertia, U-grooved measuring wheel to maximize contact and eliminate
     filament slip and breakage.
