Zusammenfassung:	Methods and apparatus for acoustic fluid valve calibration are disclosed herein. An example method involves rotating a closure member of a valve to a involves rotating a closure member of a valve to a plurality of positions along a valve stroke, obtaining acoustic emission signals generated by a fluid passing through the valve using a sensor when the closure member is in the positions, and identifying, using a processor, a zero position of the closure member based on the acoustic emission signals.
