What Are The Types Of Level Gauges And Their Applications?

Level Gauges

What is Level Gauges?

An instrument used to measure the volume of liquid in a stationary storage or processing tank is a level gauge. A gauge’s parts include the head, float, tape, bottom anchored bracket, guidance wires, elbows, anchors, coupling, pipe support brackets, and pipework. When using Level gauges, the Liquid Level Gauge Calibration is used to make sure that the right values are obtained.


Types of Level Gauges

For the intended application, different kinds of level gauges and different kinds of character traits exhibit a diversity of behavior. Common kinds of level gauges include 


  • Reflex Level Gauges 
  • Transparent Level Gauges 
  • Bi-Color Level Gauges 
  • Magnetic Level Gauges


Reflex Level Gauges

Gauge for reflex strength based on Legislation and Reasonable Rules Level Gauge

Degree gauges for reflex glass prisms are being used in the corner of Section 90 with spectacles. The cavity is filled with liquid in the bottom portion and gases and gases in the upper portion when it is operating.

The liquid level in various liquid bridges is known in the steam/glass area. A specific light is not required for reflex level gauges. The level can be seen in the daytime.


Liquid Zone 

When the gauge is on the outside face of the glass, the zone appears to be dark, indicating that it did not move through the glass. These rays are angled at 45 degrees to hit the glass/liquid interface. Up to 45 °, critical angle glass or fluid is always preferable.

The rays cannot be seen from outside because the incident of the rays within the Critical Conclusion does not reflect the gauge-interior cavity’s walls. In actuality, the zone is completely gloomy and nearly black.

Gas/Vapor Zone

This zone looks silver bright to the observer. Light waves travel toward the glass gas-vapor contact in the liquid zone at an angle of roughly 45°.


The rays make a 90° turn and return at a 45° angle to the closest glass/gas-vapor interface because this angle is larger than the glass/gas-vapor critical angle. They will reflect and be directed 90 degrees in the direction of the viewer for the same reason, giving the area a silvery glow.



Most substances and applications can be used with Reflex Glass Level Gauges.

Reflex level indicators, for instance, cannot be used:

When the process fluid is high-pressure water steam, there is a need to read the interface between the two fluids because mica shields are required to safeguard the glass from the boiler water’s solvent action.


Transparent level Gauges

Two plate-transparent glasses are always attached with transparent level gauges. Because the two media have varying levels of transparency, the liquid status is evident.

To shield the surfaces from the full operation of the liquid, the process can connect transparent level gauges with Micha Shields. Applications should be suggested to protect glass from high temperatures and transparent level gauges.



  • In a corrosive liquid.
  • The observation of the interface
  • Monitoring of liquid color
  • For an operating stressful steam> 20 bar
  • If repeated heat shocks will come


Bi-color level gauges

Boilers use bi-color level gauges to determine the media level. The gauge is constructed of premium mica sheets to protect against wet steam produced in a boiler drum. By contrasting the vapor and water indexes of refraction, the level is identified. Bi-color level gauges are transparent level gauges with a liquid chamber in a wedge-shaped portion. The gadget has two color filters, one red and the other green, in an illuminator on the back. Red light rays are deflected and absorbed to one side when they hit the ocean. The steam passes through and looks red when exposed to the same light. The reverse occurs when light passes through green filters. Users can claim that each piece of media is accessible on the system using this.


Magnetic Level Gauges

An electromagnetic field is used to regulate fluids. It is said that anything thrown into a liquid has the power to alter the fluid’s weight. It can be applied to apps with glass gauges that break or are damaged as well as apps with magnetic level gauges. They are suitable for use beneath the soil and have maximal operational temperatures and stresses, respectively. These gauges can be detected at Interface levels even in extremely poisonous or destructive media.
