摘要
超声波液位仪以其非接触的测量方式在液位测量中具有不可替代的位置,能够适应过程自动化苛刻条件要求。文中对超声波液位仪的硬件和软件设计进行了阐述。通过采用二次测量方法,提高了仪表对回波的处理能力。
Ultrasonics liquid level meter is important in liquid level measurement with its eontaetless working mode and can adapt to severe environment. This paper introduced the hardware and software of the ultrasonics liquid level meter. Using two step measurement means, the ability of processing return echo was improved.
