Volumetric level gauge

The magnetic flap level gauge is a new type of instrument that uses the magnetic steel inside the float to drive the flipping of a two-color thin sheet to indicate the liquid level. The magnetic float inside the main body moves up and down with the rise and fall of the liquid level, while driving the dual color sheet inside the indicator outside the main body to flip. When there is a liquid level, it turns red, and when there is no liquid level, it turns black. The boundary between the red and black color bands represents the liquid level height. There is a prominent scale on the left side of the indicator. At the same time, the scale on the other side indicates the volume or volume corresponding to the current liquid level. Thus achieving the display of both liquid level height and volume.
