Double Color Glass Plate Level Gauge

Summary   

Double color glass plate level gauge applies double color under light going through different mediums, it produce different reflection. Via using color filter, the light in different mediums presents a certain color. Through the glass plate, when there is liquid inside, the color is green (or natural color), while there is gas, the color is red. So, the gauge has two colors exhibition and the interface of the liquid and gas is very clear.
