OVERVIEW
The HSB dual color glass plate liquid level gauge consists of a colored glass plate, a main body, a cover plate, upper and lower needle valves, connecting flanges (or threads), and other components. It forms a connector with the container and does not require an additional power supply. It uses natural light to clearly display the liquid level height (liquid red gas white or liquid green gas white) through the colored glass plate
