摘要
介绍了超声波液位计工作原理,讨论了超声波液位计在液位测量中,影响测量精度的各种因素。并对参考声速值误差、渡越时间误差和系统时延误差的成因及影响进行了分析,提出了各种误差的校正方法。
This paper simply introduced the principle of ultrasonic wave,discussed various factors which affected the accuracy of liquid level meter,analyzed the causes and effects of reference error、transit-time error、time-delay error,and proposed correction methods of all kinds of errors.
