Reflex And Transparent Level Gauge By Flowtech Measuring Instruments Pvt. Ltd.

We are indulged in making, exporting and supplying Reflex and Transparent Level Gauges in Vadodara, Gujarat, India. FLOWTECH Instrument offers Reflex Level Gauges (optional with IBR cert.) for the Measurement of liquid level at a glance in tank. This is particularly using for High pressure OR High Temperature OR Toxic Liquid Storage Tanks. These gauges have a prism glass window that uses the basic optical principles of light refraction & reflection to enhance the indication of the liquid level. In brief when the light strikes the area of glass covered by the liquid is allow passing to the Interior of the gauge. So that the area appears dark (Black). While the light strikes the open space, above the liquid level is reflected back to the observer so that the area appears silver-white. We can clearly see the actual liquid level in the systems.

Description Of Transparent Type Level Gauge-In this type of level gauge the liquid level is discriminated in the form of different.

It is designed for safe and positive visual indication of liquid level in vessels under high pressure & temperature conditions. It is a flat glass gauge, which has precision moulded prismatic grooves cut on its inner side, which comes in contact with the medium. Light striking the glass covered by liquid is refracted (absorbed) into the liquid making this portion appear black, whereas light covering the vapour space is reflected back towards the viewer, making it appear silvery-white. Thus, a sharp clear line marks the liquid level.
Construction & Operation
Reflex (Fig.1) The liquid chamber (1) is formed by one piece metal body (2), reflex gauge glass (3), sealing gasket (4), cushion {5}and cover plate (6) all held together by u-bolts & nuts (7). The gauge glass sandwitched between the gasket & cushion is placed on front side for viewing of liquid level & held in the recesses machined in the body and cover plate. This ensures leak proof assembly, prevents gasket / cushion slippages and avoids glass to metal contact. The glass section comes in lengths from 11 5mm to 340mm and as many as 5 can be fitted in a single gauge assembly. Extended ranges can be provided by coupling two gauge assemblies through a coupler or the level gauges can be installed in a staggered manner. The level gauge is usually provided with shut - off valves at either ends to isolate the gauge in the event of glass breakage or replacement.
Transparent (Fig. 2) The construction is similar to Reflex except that the liquid chamber (01) is formed by one piece metal body and a pair of transparent gauge glass plates.
