Which Level Gauge is the Best?
As a Level Gauge Glass Supplier , share with you. Reflex Level Gauge The reflection type Liquid Level Gauge operates according to the optical principle of light refraction and relies on the fact that there is a difference in the refractive index of light entering the area where liquid exists and the area where vapor exists. The pressure gauge consists of a vertical cavity filled with fluid from a storage tank or container. The liquid level in the chamber matches the liquid level in the tank, which is determined by the interface line between the liquid in the chamber and the vapor in the chamber. The prism chamber or prism glass window is installed on the chamber. When light passes through the prism in an area with liquid behind the prism, the light enters the gauge without being reflected the observer. Therefore, the area of the gauge appears dark or black. However, when light is incident on the area behind the lens that contains water vapor (above the liquid level),...
