    Precision measuring normally requires an entrance gauge, which records the thickness of the material going into the rolling mill.  This is referred to as anticipatory automatic gauge control.  The entrance thickness gauge adjusts the rolls in microseconds if there are any changes in thickness.  The exit gauge records the thickness, and the rolls adjust based
