Zusammenfassung:	The present invention relates to a flow rate measuring method comprising: establishing a database which includes a plurality of flow profiles; measuring the flow in a flow field using a plurality of transducers wherein in between every two transducers there exists an acoustic path which indicates the flow speed of the flow between the two transducers, and a feature map can be derived from the flow speeds; comparing the feature map with the database; selecting a matching flow profile from the flow profiles wherein the matching flow profile has a plurality of weighting functions corresponding to the acoustic paths; and calibrating the flow speed using the weighting functions.
