Working Principle & Operation

Tubular level gauge employ the principle of indication of liquid level in a vessel by direct communication.

With water, a clear liquids surface is only visible through the vibration of the meniscus and with colored liquids, the visibility improves in relation to the intensity of the liquid color. Construction-wise, a tubular level compromises a transparent Borosilicate glass tube, seals, end blocks/valves, and rectangular C-channel (to protect the glass tube).
