Concept and Principle of operation
Liquid Level Gauge provides direct observation of liquid level in a tank/vessel rising and falling level of the liquid inside the
tank/vessel can be observed through the glass assembled in the gauge.
Reflex Liquid Level Gauges use the R-form sight glasses. One side surface of Reflex Glass to use flat glass has several
grooves for reflecting prism. The principle of the Reflex Glass is based on the difference in the refractive indices of liquid and
gas or in particular of water and steam. Liquid level shows conspicuously dark hard color fro liquid space and light white
color for empty space. These Reflex series are not used with a mica shield. The Reflex Gauge is assembled firmly with
gasket, reflex glass, cushion gasket and gauge cover on the body by U-bolts.
Reflex Liquid Level Gauges, designed and built for a wide range of high temperature and high-pressure applications. Our
reflex level gauge is used to make, besides other applications include observation of the level of corrosion-proof and
chromatic liquids. The most advantage of this type is for easy level reading of boiling liquids. When liquids are boiling, their
bubbles make the surface level indistinct. The manual adjustment of isolation valve at the input of the media entering the
chamber reduces the bubbling. Therefore, the level gauge ease to read the level or bubbling liquids. It also provides
advantages for highly dense and viscous liquids, as the body is made of forged construction only.
This level gauge is designed and manufactured for easy and accurate reading the liquid level of highly foamy liquids. The
gauge has a relatively spacious internal area where foamy liquid is held from forming foams.
Sealing Gaskets, Cushions and Glasses
Sealing gaskets and cushions for tight sealing at rated pressure and temperature. Tight sealing PTFE with glass inserted,
GFT and SS316 impregnated in graphite are the special features of the gaskets Electronet provides.

REFLEX LEVEL GAUGE
Special Applications.
If a conventional level gauge is used for extreme low temperature applications, it becomes difficult to observe the level of
liquid as the gauge front tends to freeze. To get rid of this problem, an acrylic non- frosting plate is mounted in front of the
gauge. So the observation of the liquid level is much easier this way.
Our Non-Frosting Reflex Level Gauges are classified depending on the process temperature, the height of the non-frosting
plate window may be selected from 80 to 250 mm.
For a jacket type requirement application. This gauge is used to read the level of high congealable or ebullient liquids. The
principle is to inflow a steam for congealable liquids and a cold water for ebullient liquids through the inside of the jacket to
ensure accurate and reliable level observation. This type is used for observing the fluid by changing it into state of liquid
after heating or cooling it through jacket according to fluid's features. Our standard is that the inlet of the jacket for steam or
cold water is ½” NPT(M) and or 15 NB flange. Others are available on request.
More severe demands may soften be required on liquid level gauges in terms of Resistance to Corrosion, and this is

REFLEX LEVEL GAUGE
Construction and dimensional cross-sectional overview
The gauge consists of a body having machined to have a liquid where high temperature are liable to occur, the glass is
toughened borosilicate glasses are used. These reflex gauges preferably used for reservoir tanks that require a relatively long
visible length by constructing the supporter.
The reflex level gauge is assembled firmly with gasket, reflex glass, cushion gasket and gauge cover on the body by U bolts.
The most advantage of this type is that it has no invisible sections (dead band). Our standard overlapped section is 10 mm as
minimum and the gauge is so designed that supporting brackets can be equipped to protect a long multiple connected gauges
from distortion of fall down. The scale plate to mount alongside the gauge may be available on request by customers to observe
the liquid level more accurately.
The gauge is used with a special reflex type gauge glass which has wider V-shaped refractive grove and red coating on the
outside of the glass. It provides a clear observation of liquid level because of made refracting red color on V-groove for steam or
beyond portion of the level and it's color of fluid itself for liquid portions.
Reflex Gauges manufactured by Electronet will provide at ease the orientation as per your convenience to have the maximum
visibility with respect to process changes i.e. level, isolation valve settings, whether any kind of leakages, leakages through plugs
for vent and drain, settings for needle/ball valves. All orientations at your process suitability with optimum results
