[0026] The cross section of the water level meter body 1 is rhombus-shaped, and two pairs of liquid level observation components are arranged on the water level meter body 1 in a mirror-image distribution.

[0027] The liquid level observation assembly includes a pressure cover 9 and a plane mirror 10. The pressure cover 9 has an observation port on its top. The water level gauge body 1 has a lens mounting groove. The lens mounting groove is connected to the water level channel 6. The plane mirror 10 is installed in the lens mounting groove through a sealing mechanism. The pressure cover 9 is pressed on the plane mirror 10 and is detachably installed on the water level gauge body 1 through a set of bolts.

[0028] The sealing mechanism is composed of a sealing ring, an anti-corrosion pad and a protective pad. The sealing ring is located at the bottom of the lens mounting groove. The anti-corrosion pad and the protective pad are placed above the sealing ring. A buffer pad is arranged between the pressure cover 9 and the plane mirror 10.

[0029] The water level meter body 1 is installed in a protective shell 11 , and a pair of glass lenses 12 are arranged on the protective shell 11 .

[0030] A lampshade 13 is disposed on one side of the protection housing 11 , and a pair of light emitting lamp groups 15 are disposed in the lampshade 13 . The light emitting lamp groups 15 are composed of a green cold light source diode and a red cold light source diode.

[0031] A plurality of observation windows 14 are arranged in a staggered manner on the protection housing 11 .

[0032] Valves are respectively provided on the gas pipeline 3 and the water pipeline 4.

[0033] A drain valve is provided at the bottom of the balance pipe 5.

[0034] A plurality of groups of heat dissipation fins are arranged on the outer wall of the condensation tank 2, and the tank wall at the upper portion of the condensation tank 2 is thinner than the tank wall at the lower portion.

[0035] Embodiment 1: As attached Figure 1 As shown, the boiler 100 has liquid in the lower part and high-temperature gas in the upper part. The water and gas in the boiler 100 enter the balance pipe 5 respectively. The gas and liquid reach a gas-liquid equilibrium state in the balance pipe 5. The gas enters a pair of gas delivery pipes 7 from the upper gas delivery pipe 3, and then enters a pair of water level channels 6. The liquid enters a pair of water level channels 6 from the lower water delivery pipe 4. The gas and liquid reach an equilibrium state in the water level meter body 1. At this time, the lampshade 13 is located behind the observation window 14. The protective shell 11 is provided with scale lines. The power of the light-emitting lamp group 15 is turned on. When the liquid level rises, the refraction angle of the red light increases and the refraction angle of the green light decreases, resulting in a change in the display ratio of the two colors, thereby intuitively displaying the liquid level height. The gas is transported to the condensation tank 2 along the pair of gas delivery pipes 7. The gas is cooled in the condensation tank 2 to form condensed water. The condensed water flows along the gas delivery pipe 7 into the pair of water level channels 6 to wash the plane mirror 10, so that the plane mirror 10 is not easy to be fouled. The tank wall at the upper part of the condensation tank 2 is thinner than the tank wall at the lower part, so that the condensation speed is faster, and the amount of saturated water added to the water level channel 6 is large, so that the water level difference in a pair of water level channels 6 is very small.
