发明名称	Method to measure flow characteristic of medium in open gutter or partly filled pipe
摘要	The method involves transmitting two successive short ultrasound signals at least partly in the flow direction. Echo signals from parts of each ultrasound signal, which are scattered by inhomogeneities, are received in two successive specified time window, corresponding to two position windows. The two echo signal courses are digitalized and stored. A cross relation is formed between one or more regions of the two echo signal courses.
