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, NON-ASVESTOS, etc.
Reflex Gauges:
These 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, 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 behaviour 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.
