GLASS PLATE DUAL COLOUR LIQUID LEVEL GAUGE

The utility model belongs to a liquid level indicating instrument for liquid containers, and provides a glass plate dual color liquid level gauge. The liquid level of the glass plate near the liquid is provided with a long handle with a V-shaped cross section, and both sides are painted with film color filters made from colored transparent materials. After the light is beamed into the glass plate from both sides, the part higher than the interface and the part lower than the interface present different colors because of the reflection and refraction action of different media, so as to clearly observe the position of the liquid level.
