导波雷达液位计是基于时间行程原理的测量仪表，雷达波以光速运行，运行时间可以通过电子部件被转换成物位信号。探头发出高频脉冲并沿缆式探头传播，当脉冲遇到物料表面时反射回来被仪表内的接收器接收，并将距离信号转化为物位信号。
Guided wave radar liquid level meter is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into material level signal through electronic components. The probe sends out high-frequency pulse and propagates along the cable probe. When the pulse meets the material surface, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into the material level signal.
