超声波流量计中的数据处理

Data processing of ultrasonic flowmeter

在超声波测量系统中，利用相关技术来处理采集所得数据信号是一种非常普遍的方法。本文采用了相关的直接法和快速法来处理数据，还提出了一种与相关类似的数据处理方法，最后给出了３种方法对超声流量测量的数据处理结果。

It is a general method to apply the correlation technique to dealing with the signal data acquired in the ultrasonic measurement system. The fast processing method and direct processing method were both employed. A new method smilar to the correlation was presented At the end of the article, the results of the three methods of data processing in ultrasonic flow measurement were compared.
