SMF300 Magnetic level gauge main body tube is connected to the liquid storage tank through a flange. As the liquid in the container changes up and down, the float containing the magnetic steel is driven to move up and down. In the fully enclosed tube, only the float moves up and down with the liquid. Outside the main body tube It is a magnetic flip column, half of the magnetic flip column is white, and the other is red made of plastic.
The high temperature resistance is made of ceramic material. The distance between the shafts of the magnetic flip column is 10mm. As the float moves up and down, the beam magnetic field of the permanent magnets in the float will push the column to 180 °C, thus changing their color. When the float rises, the magnetic flips change from white to red, and when the floats fall, they turn white again, which means, at any time. The red or blue magnetic flip column always represents the liquid in the tank without the need for an external power source.
