Tubular Level Gauges

Utilising the basic principle of - liquids find their level - tubular level gauges have been the most preferred and economical means of direct liquid level indication since time immemorial. Various means of glass tube protections- 3 plate glass protection, 3 guard rods, pipe guard or C-channel protections are in popular use. Our level gauges have C-channel protection of 2 mm thick sheet metal, making it robust and sturdy.

A black powder coated aluminium engraved scale with white numerals & markings is provided for indication of the level of liquid in millimeter or Litres as required. Scale shall have minimum graduation of 5 mm.

Process connections can be threaded or flanged to customer specifications. Isolating cock valves/needle valves or isolating needle valves with safety ball-check protection to prevent spilling/leakage by automatic shut-off in the event of glass tube breakage- are optional features.
