These flat glass level gauges are constructed with a solid forged steel bar main chamber and cover plates recessed to have perfect alignment of gaskets and glass. Though rated for #2000 psig rating, these are light weight and hence do not need any cumbersome supports for medium lengths. With special main chamber construction these gauges can be supplied up to #3000 psig rating. Main Chambers are available in forged C.S, M.S, SS304, SS316, P.P., P.V.C., FRP and Rubber lined. Gaskets are of CAF, GRAFOIL, TEFLON, NON-ASBESTOS, etc.
WHY FLAT GLASS LEVL GAUGES?
You have designed your vessels with utmost care of getting the maximum economy. Also your investment on each vessel will be considerable. The return on your investment, should in no way, be hampered by defective Level gauges. Your level gauge should have the same strength as your vessel to withstand the high pressures to which it is subjected and the corrosive characteristics of the fluid. Also, your valuable process fluid should never leak out through the glass fitting, which is quite common in most of the tubular glass level gauges available in the market.
In industries, you may have to measure the levels of colorless liquids, interface of immisible fluids, liquids with sub-zero temperatures and liquids with too much foaming. All these requirements can be met with by our latest types of flat glass level gauges.

FLAT GLASS LEVEL GAUGES
These gauges are constructed with a solid forged steel bar main chamber and cover plates recessed to have perfect alignment of gaskets and glass. Though rated for 2000 psig. These are light weight and hence do not need any combursome supports for medium lengths. With special main chamber construction these gauges can be supplied upto 3000 psig. Main chambers are available in C.S, M.S, SS304, SS316, P.P, P.V.C, FRP and Rubber lined. Gaskets are of CAF, GRAFOIL, TEFLON, etc.
REFLEX GAUGES:
These are assembled with flat glasses with inner surfaces of reflecting prisms. Due to total internal reflection reflection liquid level shows black in contrast to a mirror-like surface above, The gauges are used for services where observation is required at a distance and on low pressure boilers.
TRANSPARENT GAUGES:
These are assembled with two numbers of totally transparent toughened glasses to give a through vision of liquid levels. These gauges are recommended for interface levels, coloured fluids where colour is of interest to the process behavior and services where excessive foaming may exist. In high pressure boilers these gauges are recommended to be used with mica shields.
GLASS:
Teleflo engineers continuous research, development and experimental studies on glass toughening and composition has made the tempered glasses used in these gauges most dependable providing a high strength resistant to both thermal and mechanical shocks and with the highest degree of visibility.
SPECIAL LEVEL GAUGES:
Teleflo offers level gauges for every kind of application in the process industry and the following are very widely used. Apart from the types detailed below Teleflo can offer level gauges with rubber lining, lead bonding, steam traced and also with Boiler Inspector Certificates. Teleflo has already supplied to leading Indian Industries number of Boiler level gauges and are now planning a standardization of the centre to centre distance of gauges used in Boiler in this country.
NON-FROST GAUGES:
For cryogenic services where formation of frost on the gauge may cover the window, non frosting extensions made out of clear transparent perspex sheet prevents frost from covering the windows and thereby maintains clear visibility at all times. The frost shield extends beyond the cover plate by 2” or more as per the service temperature. The cover plate of the gauge clamps the flanges extension to the glass, thus maintaining direct contact with the gauge glass so that frost is prevented from forming. No sealing or drying agent is required. The flanged base of the frost preventing unit is surrounded by a gasket, so that, in case od accidental breakage of the forst preventing unit, the torque of the cover bolts will be maintained and leakage will not result. Non frosting gauges are available both in reflex and transparent types.
LARGE CHAMBER GAUGES:
TELEFLO large chamber gauges are for boiling liquids having a tendency to surge, These gauges are recommended for liquids with high rate of bubbling and vapouring liquids. If the liquid being gauged has an unusually low boiling point, the gauge and valves should be insulated and the gauge equipped with a non-frosting unit.
TELEFLO large chamber gauges are for flat glass reflex or transparent design. The main chamber is out of 2”NB seamless pipe with suitable gaskets and cover plates. All parts are rust proofed. These gauges can be supplied to a maximum pressure rating of 40 kg/cm square.
Reflex Level Gauges:
Fluidyne Reflex Level Gauges are assembled with flat glasses with inner surfaces of reflecting prisms. Due to total internal reflection liquid level shows black in contrast to a mirror-like surface above, These gauges are used for services where observation is required at a distance and on low pressure boilers.
Transparent Level Gauges:
Fluidyne Transparent Level Gauges are assembled with two numbers of totally transparent toughened glasses to give a through vision of liquid levels. These gauges are recommended for interface levels, colored fluids where colour is of interest to the process behavior and services where excessive foaming may exist. In high pressure boilers these gauges are recommended to be used with mica shields.
Large Chamber Level Gauges:
Fluidyne Large Chamber Level Gauges are assembled with flat glasses with inner surfaces of reflecting prisms or two numbers of totally transparent glasses and are suitable for boiling liquids. These Large Chamber gauges are used for services where clear observation is required for boiling or unstable liquids.
