Transparent Level Gauge

Introduction:The SCS Level gauges are used for measuring the level in the vessel.These can be used for maximum pressure of Upto150kg/cm² and a maximum temperature of 400°C. Constructional features include 2.5 meter single piece construction with multiple glasses between process connection. A pair of auto shut off ball check valves in material of construction carbon steel or stainless steel and polypropylene as optional.

Principle :

Transparent gauges employ two transparent glasses and a liquid chamber. The liquid level is indicated as a result of difference in the transparent properties of the two media. For water/steam application, an illuminator is mounted on the rear side of gauge with its light rays deflected upwards into the water column. These enable the observer to see the illuminated surface of the water as the light rays impinge on the surface of separation between water and steam is reflected back to the eye of the observer. For high temperature application mica shield is used. Special feature is that liquid column in chamber is illuminated using illuminators.
Max press: 150kg/cm²     Max temp: 400°C.

Note: in these Gauges, glasses are with four side smooth finished flat surface.
