Abstract
A system and method for automatically calibrating the flow measurement device of a locomotive air brake control system. The air brake control computer controls activates a magnet valve to create a predetermined flow from the brake pipe through an orifice to exhaust, thereby creating a reference flow value to enable the calibration of the flow measurement device. The system reduces the likelihood of human error and variability by automating the steps necessary for flow measurement calibration under computer control.
