The double color display of ULB-S double color glass plate level gauge is based on reflection and refraction characters of light in different mediums. Via color filter, the characters presents a certain color. When there is liquid inside, the color will be green (or natural color). When there is gas, the color will be red. So, the gauge has double-color indication and the interface of the liquid and gas is very clear.
