在判断管道内液体是否存在方面一直没有相应的检测有效手段，现有的超声波和电磁式测量等技术方法都是基于流量检测的，可以检测管道内液体的流量大小，但是对于流速较幔或者液体静止的情况，测量效果不明显；传统的机械武流量开关因为传感器探头有运动固件存在于管道中，可能对液体流动造成干扰，甚至在液体有腐蚀性或污浊时出现误判断或者损坏。本文主要是针对于流速慢或者静止状态下检测情况，研究一款能用于煤矿井下的液位检测传感器。

There has been no corresponding effective detection method in judging whether the liquid in the pipe, the existing ultrasonic and magnetic measurement technique is based on flow detection, it can detect the flow liquid in the pipe.But for flow velocity slower or liquid static, the measuring error is bigger; because of the sensor probe have structure parts in pipeline, the traditional mechanical flow switch might be impact on liquid flow, the probe will have wrong judgment or damage in corrosive and dirty liquid.Mainly based on flow velocity slow and liquid static detection, research and design the liquid-level detection sensor can be used to coal mine.
