Magnetci level gauge is used to test liquid level of media in storage devices（tower,vat,trough,ball-shape container and boiler)under pressure or open.It could indicate status and height of various liquids. The liquid level  signal could be transmitted from long distance with connection of the indicator and liquid level transmitter. With certain electric devices, automatic control& measuring of liquid level could be realized.

Its based on the principle of buoyancy and magnetic coupling. While level in container changes, the floating ball and the connected permanent magnetic steel moves which make the column overturned by magnetic coupling. When the level rises, column turned from white to red, when the liquid level drops the color change from red to white. The boundary is the actural height of the medium in container. The liquid level can be displayed automatically in this way.
