Glass Plate Level Gauge

Glass plate level gauge is divided into three kinds: Transparent type, reflection type and Sight Glass type. 

The level gauge is mainly composed by level gauge's body, upper valve (gas valve), lower valve (liquid valve),drain valve, insurance steel ball and so on. 

When the glass plate have some cracks or be damaged, the insurance steel ball will automatically stop the side valve of gas and liquid to avoid or reduce flowing.

So the worker can cut off the bottom valve to handle it. 

This series product is stable, sealed and reliable, simple installation, which is ideal instrument for detecting for liquid level in all kinds of containers with middle or low pressure. Connecting the upper and lower flanges of this level gauge with the upper and lower flanges of the container to form a permeator, then the height of liquid can be directly seen.

The principle behind the Reflex Level Gauge is based on the difference in refractive index between the liquid in the tank and the liquid in the chamber. 

The refractive index change causes the reflection of light at the liquid-glass interface, making the clear space visible. 

This allows the operator to visually determine the liquid level in the tank.

Reflex level gauges are commonly used in industries such as oil and gas, chemical processing, and power generation, where accurate and reliable level measurement is essential for operational and safety purposes.
