Summarize
The intelligent universal electric contact liquid level monitor is an electric contact type liquid level measuring, displaying and controlling instrument composed of measuring cylinder, ultra-pure ceramic electrode and display instrument.
It uses a red and green two-color light emitting tube to simulate steam (red) water (green) in the display, obviously indicating the position of the liquid level in the container, and has the function of alarm and output.
The electric contact level monitor is suitable for the level measurement and control of conductive liquids. It is mainly used for monitoring boiler bubble water level, high and low pressure heaters, deaerators, evaporators, condensers, direct current boiler starting separators and other water tank level measurement. But not suitable for flammable and explosive occasions.
