提出了一种新型的夹持式超声波流量计的设计方法。应用空间频率分析方法对宽波束进行了理论分析。结果表明，管壁中产生的平板模态对流量测量有很大的影响。这种方法可以减少这种影响。该方法可以自动补偿温度变化引起的传输路径偏差，并在声速未知的情况下测量流量。<<ETX>>
A novel method of a clamp-on ultrasonic flowmeter is proposed. With this method, a widebeam is examined theoretically by the application of spatial frequency analysis. It is demonstrated that plate modes generated in a pipe wall exert bad effects on flowrate measurement. This method can reduce such effects. This method makes it possible to automatically compensate for the deviation of the transit path caused by the temperature change, and to measure the flowrate even if the sound velocity is unknown.<<ETX>>
