Designing And Working Of Reflex Level Gauge

Posted by Admin on November, 19, 2014

The Reflex Level Gauge is a direct level gauge that finds its applications in the containers and steam boiler applications. It is designed to provide a safe and positive indication of the liquid level in vessels operating under high pressure and temperature conditions. It has precision molded prismatic grooves engraved on the inner surface. This surface comes in contact with the liquid and the light hitting on the glass portion is refracted. Due to the refraction, the glass portion covered by liquid appears black and the glass portion covered by the vapor space appears silvery white. This creates a clear and sharp lining in the liquid eliminating any chances of error in reading.

Designing Of The Reflex Level Gauge:
The machine offered by the Reflex Level Gauges Manufacturer is a robust metal body comprising of an internal chamber and more than one front window on one side of the gauge. A highly resistant plate reflex glass is fitted on each of the window with sealing joint and metal cover plates supported by bolts and nuts. The chamber is connected to the vessel with the help of flanged, cross fitting, welded or threaded ends.

Usually, valves are fitted into the instrument and the connecting ends. They are fitted to permit shut-off piping and disassemble level gauge without emptying the vessel. Moreover, drain valves can also be fitted to the cross fitting device. Further, Safety ball check device can be provided to prevent leakage in case of glass breakage.

Working Principle Of Reflex Level Gauge:
The Reflex Level Gauge works on the principle based on the reflection laws and light refraction. It uses glasses with its face fitted towards a chamber. This chamber is shaped with prismatic groves with 90° section angle. The chamber has two zones which are filled when in operation. The lower level of the chamber is filled with liquid while the upper level is filled with vapors and gases. The level of the liquid is indicated with the glass brightness in the liquid, gas or vapor zone.
