Two - color water level gauge is mainly used for all kinds of pressure vessel, industrial steam boiler level display. It is more safe and reliable than the original two-color quartz tube level gauge, more clear display, more convenient maintenance and repair. It overcomes the shortcomings of the original product in weak natural light must be with power supply, and its appearance both from the volume or weight are much smaller than the original, the overall feeling of the instrument is small and novel.

Liquid level meter is the use of light in different media present different refractive index and reflection characteristics, and with the help of the color filter liquid phase is green, gas phase is red two-color display, the gas-liquid interface is very clear.

Liquid level gauge is a local liquid level measuring instrument mainly used to directly indicate the height of medium liquid level in various tanks, towers, underground storage tanks and other open tanks with pressure vessels in the process of industrial production. With eye-catching liquid green gas red two-color display and excellent acid resistance, it successfully overcomes the shortcomings of the existing plate or tube type liquid level meter which can not be judged when full liquid or no liquid. The main difference with ordinary glass tube level meter is the use of high temperature, high pressure quartz glass tube and more reasonable structure, therefore, can be competent for all kinds of high temperature, high pressure, ultra-low temperature, ultra-low pressure and acidic occasions. Especially suitable for two kinds of mixed not easy to distinguish media such as oil water and water, liquid gas water and other media.
