电极式氖灯水位计是电极式水位计中线路、结构较简单的一种二次显示仪表。它完全可以自行设计、安装和试验。可广泛应用于除氧器、加热器、蒸发器、凝汽器、汽鼓、汽水分离器等设备的水位测量与监视。1氖灯水位计测量原理测量原理如图所示。由图可知，氖灯3的一端接电极芯2，另 Electrode-type neon water level meter is electrode type water level meter in the circuit, a simple structure of a secondary display instrument. It is completely self-designed, installed and tested. Can be widely used in deaerator, heater, evaporator, condenser, steam drum, water separator and other equipment, water level measurement and monitoring. A neon light water level meter measuring principle measurement principle shown. It can be seen from the figure that one end of the neon lamp 3 is connected to the electrode core 2 and the other
