Reflex Flat Glass Level Gauge


We are among the prominent Reflex Flat Glass Level Gauge Manufacturers and Suppliers. The Reflex Flat Glass Level Gauge provided by us is made of best quality raw components that help in enhancing its performance levels. It is designed for safe and positive visual indication of liquid level in vessels under high pressure & temperature conditions. The Reflex Flat Glass Level Gauge is a flat glass gauge, which has precision molded 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 vapor space is reflected back towards the viewer, making it appear silvery-white. Thus, a sharp clear line marks the liquid level.


Made Of
  • Tempered Borosilicate Glass, resistant to chemicals, thermal & mechanical shocks
  • Large Chamber for boiling, foaming, flashing or surging liquids
  • With offset needle valve, the centerline of the gauge and drain connections offset 22 mm from the centerline of vessel connections. Hence by removing the vent/ drain plugs, the interior of a top & bottom connected gauge glass may be cleaned without removing the gauge
  • Safety Ball check

Construction and Operation
  • Reflex : The liquid chamber is formed by one piece metal body, reflex gauge glass, sealing gasket, cushion and cover plate all held together by U-bolts & nuts. The gauge glass sandwiched 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 : The construction is similar to Reflex except that the liquid chamber is formed by one piece metal body and a pair of transparent gauge glass plates.
  • Function Of Autoball Check : Autobail "check facility is provided to prevent “liquid loss" from vessel during breakage of gauge glass. It consists of a capsule located along the 'neck’ of the gauge and contains a 'ball’, which moves freely along its inner race, between the stopper & orifice. During breakage, the pressure on 'ball' from gauge side will be atmospheric, whereas higher pressure from the vessel side ("operating pressure + liquid column") will cause the ball to move and block the orifice whereby liquid loss will be minimized.
