Bicolour/colour port type level gauge
Bicolour and colour port level gauges are basically through vision type level gauges having a taper type gauge body to get the bicolour effect.

Features

• Imported superior borosilicate glasses (Aluminosilicate disc glasses in case of colour port type)
• Standard or 3 piece cover (for bicolour type), for high pressure applications.
• Ball check arrangement as optional.
• Engraved aluminium /stainless steel scale (optional)
• Good visibility even upto 20 M below vessel location.
• Chain operated valves if reqd.
• Expansion loops in case of high pressure and temperature applications.
• Tie-bar/stand pipe for added robustness, more compactness and better circulation.
• High quality forged parts in carbon steel/stainless steel.
• Non-flameproof or flameproof illuminators (as per IS 2148:1981 for Gr. IIA, IIB or IIC gases) fitted in stainless steel costings.
• High quality (stained 'first' quality or 'A' quality) mica.
• IBR/Lloyds certificate (if required)
• Colour port type visibility per port is 20 mm and centre to centre distance between adjacent ports in normally 75 mm.
  

Applications
Clear non-viscous liquids, normally used for boiler drum level indication, specially when level is required to be observed at operation floor level.
