The two-color mica water level gauge is a one-time direct-reading instrument for monitoring the water level of steam boilers or other pressure vessels in power plants, petrochemical and industrial and mining enterprises. It is the latest development based on various trans-missive two-color water level gauges at home and abroad. A new type of two-color water level gauge of, the water level gauge has the characteristics of high measurement accuracy, good observation effect, and long service life of window components.
The self-flushing two-color water level gauge is a functional design of the body on the basis of the traditional two-color water level gauge, adding a strong flushing function.
A condenser can be added to the top of the water level gauge body, the inside of the condenser is separated by a partition with a middle hole, and it is biased to the outside. The partition is to prevent the condensate from flowing to one end, and the deviation to the outside is because the outside temperature is low, and the formation of condensate is fast. The purpose is to prevent the condensate from flowing in the two rows of windows. When the saturated steam in the steam drum flows through the condenser, the heat dissipation function of the condenser is used to form a large amount of salt-free pure water. The dirt attached to the mica in the observation window is washed away. More importantly, the formed large amount of purified water flows back into the body cavity and continuously replaces with the saturated water in the body. Finally, the saturated water in the body cavity becomes pure water without salt and impurities, so that the window is free of scales. The color is high-definition and long-lasting, which improves the observation effect and prolongs the service life of the window assembly.
The light emitted by the light source passes through the red and green filter lenses and is directed to the liquid cavity of the water level gauge body. In the vapor phase of the cavity, the red light is directed straight ahead, while the green light is absorbed obliquely to the wall. In the liquid phase part of the cavity, the green light is directed toward the front due to the refraction of the water level, while the red light is directed obliquely to the wall. Therefore, when viewed directly in front, the display shows red, green, and steam.
