Zusammenfassung:	A system and method for calibrating an ultrasonic flow meter. In one embodiment, a method includes disposing a fluid circulating device within a flow meter. Fluid is circulated in the flow meter by operation of the fluid circulating device. An acoustic signal transit time within the flow meter is measured during the circulating. Based on the measuring, a portion of the acoustic signal transit time caused by latency induced by components of the flow meter is determined.
