Types of Level Gauge
Tubular level gauges:
Suitable for monitoring non-toxic, low-pressure liquids.
Reflex level gauges:
Indicate the level in a tank using the optical principle of light refraction in a transparent glass element. They are ideal for monitoring clear liquids that would otherwise be difficult to see.

Transparent level gauges:
These are similar to reflex gauges, as they also work by refracting light. The main difference is that they use two glass elements to allow light to pass through.
Two-color level gauges:
These are used to detect the level of water and steam in a boiler. They rely on the optical principle of light refraction through two colored optical filters, each with a different refractive index.

No need for a level bridle. The bypass chamber containing the float acts as a bridle allowing accessories to be mounted on it.
High-pressure capability, with many manufacturers offering gauges suitable for pressures up to 400bar.
High-temperature capability. Applications up to 450°C not uncommon.
Use in hazardous areas. Because magnetic level indicators do not need an external power supply, not even for an illuminator, they are suitable for installation in hazardous areas.
Maintenance free. Magnetic level gauges are virtually maintenance free because the indicator never touches the process fluid. With sight glasses, the gauges must be periodically checked for leaks and cleaned on a regular basis.
No worries about broken glass. This makes them ideal for measuring levels of toxic and corrosive liquids.
Easily heat traced and insulated. An important consideration depending on the fluid being measured.
