3. Working Principle and Structural Characteristics

3.1 Working principle: this series of dual-color water level meters are connected with the steam drum from upper steam drum and bottom water valves. The water level in the level meter is consistent with the water level of the steam drum.
3.2.the water level gauge is mainly composed of body, mica, after assembly, plate, high strength bolt, LED cold light source assembly (LED cold light source box, insulation box cover, observation, switching power supply) (specially formulated for LED cold light source), balance tube, high pressure valves and other components. (see map).
33 the observation window of the water level meter has a 280mm observation window on the central line of the surface to detect the blind area.At the same time, through the principle of optical reflection and refraction, the red and green light emitted by the red and green LED light source lamp are fired into the observation window of the mica water level meter body, respectively, so that the operator can be on the spot in the boiler drum.Or through the industrial television monitoring system in the centralized control room on the display can be directly and clearly observed the situation of the drum water level, observed steam red, water green, steam full red, water all green display effect

3.3.2 The structure of the double color water level meter for B69H-10~22-3 observation window is like the following picture

3.3.3 The structure of B69H-10~22- 5 double blind water level meter without blind area is as follows:

structure. Prevent fouling in the observation hole. The use of a long period.
