Reflex gauge glass is used to read the medium level in the boiler or other tanks. The one side of the glass which is exposed to the medium has a prismatic surface and another side is smooth. The medium level inside the level gauge is indicated as the result of the light refraction principle, since the liquid filled area completely absorbs the rays of light and appears dark, whereas the rays of light are totally reflected in the gas/air filled area which appears bright.
Reflex gauge glass is made from high borosilicte glass. It has many advantages, such as cheap, low maintenance cost, easy level reading and excellent high temperature & pressure resistance. Its working pressure can be up to 4 MPa and working temperature can be up to 430 C. The edge can be polished or frosted.

Reflex Level Gauge
WORKING PRINCIPLE
Reflex glass level gauges working principle is based on the light refraction and reflection laws.Reflex Level GaugeReflex glass level gauges use glasses having the face fitted towards the chamber shaped to have prismatic grooves with section angle of 90�°. When in operation, the chamber is filled with liquid in the lower zone and gases or vapors in the upper zone; the liquid level is distinguished by different brightness of the glass in the liquid and in the gas/vapor zone. The reflex level gauges do not need a specific illumination: the day environmental light is enough. Only during the night an artificial light must be provided.

The different brightness in the two zones is obtained as explained below:

LIQUID ZONE
This zone appears quite dark when the gauge is in operation and lighted as above said.
Given the construction, most of the environmental light rays incident on the external face of the glass are quite perpendicular to said face and, therefore, not deviated by the glass. These rays reach the glass/liquid interface with an inclination of approx. 45�°. The critical angle glass/liquid is always superior to 45�°. Therefore the rays incident within the critical angle (practically the totality) are refracted within the liquid and, since the internal walls of the gauge chamber are not reflecting, the rays cannot be seen from the outside. In fact the zone will appear dark, nearly black, to the observer.

GAS/VAPOR ZONE
This zone appears almost silver bright to the observer.
As for the liquid zone, the light rays reach the glass/gas-vapor interface with an angle around 45�°. Since this angle is greater than glass/gas-vapor critical angle, the rays are not refracted , but totally reflected making 90�° turn, thus reaching the nearest glass/gas-vapor interface again with angle of 45�°. For same reason they will be reflected and turned by 90�° towards the observer, to whom the zone will appear silver bright.

APPLICATIONS
Reflex glass level gauges can be used in most of the cases and offer great advantages in terms of: low initial cost, low operating cost, easy level reading.

Reflex level gauges cannot be used in certain cases as for example:

when the separation level between two liquids has to be read (interface).

when besides the level indication, the observation of the liquid colour is required.

when the process fluid is high-pressure water steam, since in this case the glass must be protected from the solvent action of the boiler water by using mica shields.

when the process fluid is such that can corrode the glass (e.g. high temperature alkaline solutions or hydrofluoric acid), since ica shields or Polytrifluorochloroethylene shields must be used to protect the glass.

Transparent Level Gauge
Working Principle

Transparent level gauges are always fitted with two plate transparent glasses between which the fluid is contained. The fluid level is indicated as the result of the different transparency of the two media and in some cases (for water steam), by conveying upwards on to the surface of separation (between liquid and gaseous substances) a source of light located at the back of the gauge, the rays of which are totally reflected down to the observer.Transparent Type Level Gauge

We can provide the corresponding level glass, please refer to the related products.

APPLICATIONS
Transparent level gauges are suitable for almost all installations.
In fact they permit:

the use of mica shields or Polytrifluorochloroethylene shields to protect the glass from the corrosive action of the process fluid

the observation of interface

the observation of the liquid colour

This instrument consists of a metal body, machined to have an internal chamber and one or more front windows (on each side of the gauge). On each window a special high resistance plate transparent glass is applied with sealing joint and metal cover plate hold by bolts and nuts.

The chamber is connected to vessel with cross fittings and flanged, threaded or welded ends. Usually, between the instrument and its connecting ends, valves are fitted to consent shut-off piping and to disassemble the level gauge without to empty the vessel. Drain valves can also be fitted to cross fittings device.

To avoid leakage in case of glass breakage, safety ball-check device can be provided in cross-fittings or shut-off valves. This kind of indicator is suitable for water/steam. To protect glass surfaces from corrosive action of the process fluid, Transparent Level Gauges can be fitted with Mica shields or Polytrifluorochloroethilene shields. This kind of indicator is suitable for liquids colorless and very fluid.

In some case (i.e. for water / steam) the best reading is obtained by conveying upwards on the surface of separation (liquid/steam or vapor interface), a source of light, located on the back of the gauge, the rays of which are totally reflected down to the observer.

These work on the principle of difference in reflective indices of liquid in the tank and possible presence of gas with the liquid. The liquid will be black display while the gas or vapor will be white display.

These level gauges have glass etched with reflecting prisms at inner surface. This surface reflect the light falling on the surface and enable detection of surface of even colourless liquids.

Operating Principal: The Principall of the Reflex Gauge Glass is based on the difference in the refractive indices of liquid and gas or in particular of water and steam. It has prismatic right angled grooves,on the side facing media.if a ray of light encounters the surface of one of the 450C slanted grooves in the gas or steam space it is reflected to the opposite surface of the groov and from there totally refiected back into the direction of observation The steam or gas space therefore appears as silver - white

The light ray which encounters the surface of a groove in the liquied space is almost totally absorbed.The liquid behind the reflex glass therefore apperars black. Light rays entering from outside the gauge are either absorbed or reflected depending opon whether they enter the water or steam space

(Serveral sizes are available in both Transparent Gauge Glass & Reflex Gauge Glass

Round sight glass, also called round gauge glass and sight glass disc, commonly uses the material of soda-lime glass, borosilicate glass, aluminosilicate glass and quartz glass. We suggest different material according to environmental conditions, such as temperature, pressure, acid and alkali.



Soda-lime glass working temperature is up to 230 �°C, but it is the most inexpensive material. Borosilicate glass is particularly used in aggressive environment, such as acid and alkali. The working temperature is up to 400 �°C. Aluminosilicate glass can resist acid and alkali better than borosilicate glass and the working temperature can reach 650 �°C. Quartz glass is the best material, whose working temperature can reach 1100 �°C.



Round gauge glass is commonly used in industry, chemical, petrol and medicine pipes and flanges for observing the liquid flow and liquid level.



Round glass Data Sheets



Quartz round glass can be processed and produced according to customer requirements, using different materials of JGS1, JGS2 and JGS3.
