glass liquid indicator

Detailed Product Description

One. Generation:

TBS-A glass sheet level gauge displays the liquid level in the closed container of  tank,pot,tower,box at normal pressure. They are widely used in chemical, industries, petroleum ,electricity, food,water factary etc.

Two.structure and principle

The liquidometer is composed of the main body, the lap, the top and bottom needle valve, the glass plate, the connection flange (or thread) .The connection flange (or thread) and vessel make connected vessels.We can observe the liquid level through glass sheet. the security steel ball Is loaded between the top and bottom needle valve to prevent the glass plate damaged by accident, the steel ball starts the sealing liquid channel due to the pressure, plays the automatic seal function.
