The Maxtec flow meters are specifically designed to work with blenders. These DFB flow meters are calibrated for the pressure drop that is associated with a blender as flow rates are increased. This is specially important in the world of high flow.
Every Maxtec DFB flow meter has a dual scale, which essentially combines 2 flow ranges into 1 flow meter. The dual taper allows accuracy from the lowest visible ranges, to high flows. This eliminates the need for multiple flow meters attached to a blender.
