中文摘要:
      本文论述了将D82A数据采集卡应用到超声波氯气流量计中,通过对采集数据的分析,精确地确定超声波传播的声时和声时差。本文主要是讨论数据处理的方法。最后,作者对结果进行了讨论并和其它超声波测流量的方法作了比较。
英文摘要:
      In the paper, the application of D82A acquiration card to ultrasonic chlorine flowmeter was introduced. By dealing with the signal data acquried by D82A acquiration card, the flight time and flight time’s difference came out accurately. The paper focused on the way to process the signal data. In the end, the author discussed the result and compared some other ultrasonic technique to flow measurement with the way in this paper.
