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

We are reliable Manufacturer and Supplier of Tubular Liquid Level Gauge. The Tubular Liquid Level Gauge is made from good quality raw components that help in making it durable and give perfect results. Tubular type Level Gauges are used for direct level indication in Tanks and Vessels under Pressure and Temperature. Construction Of The Tubular Liquid Level GaugeThe top and a bottom fitting can be fixed on suitable nozzles or bosses at top and bottom of a Tank with a Glass Tube fitted between them. The liquid level in Glass Tube indicates the level of liquid in Tank. The top and bottom Valve fittings can be provided with Isolating Needle Valves Handwheel operated. The minimum Centre to Centre Distance is about 600 mm. Top fitting can have Vent Valve (Needle type Valve) instead of Plug (normally NPT/BSP). Similarly bottom fitting can have Drain Valve. The end connections can be Flanged (normally 20/25 NB Flanged to BS/IS/ANSI/DIN Standard) or Socket Weld type (3000 psi rated normally 20/25 NB) or Screwed type through Union (20/25 NB BSP/NPT- Male; can be Female also). The material of construction can be Carbon Steel, Stainless Steel (SS-304)/316), PVC, Polypropylene, etc. Maximum Hydraulic Test Pressure is 3 Kg/cm² in case of PVC / Polypropylene material of construction. The fittings can be Fabricated (Carbon Steel, SS-304/316). The Valves have Screwed Bonnets. Valve Packing can be Graphoil, Teflon  Ring or Teflon Rope and Glass Tube Packing can be Graphoil, Rubber Cone, Teflon Ring or Teflon Rope. Top and bottom fittings are provided with Safety Ball Sealing arrangements to prevent gushing out of liquid and gas under pressure in case of Glass Tube breakage. Needle Valve Spindles are provided with End Pins to disengage Ball if gets stuck in Closed position. For Glass Tube protection against mechanical damage, Twin mild Steel (Epoxy painted) Protector, Metal Tube Protector, 4-Guard Rod Protector (with or without Wire Mesh wrapping) or 3-Glass Protector can be provided. Tubular Level Gauges are normally not recommended for Pressure and Temperature higher than 15 Kg/cm² and 200^oC. Function Of Autoball CheckAutoball 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. InstallationSide mounted through tank nozzles, having matching counter flanges / threads, ensuring that CC distance between nozzles corresponds with CC distance (R) of the gauge.
