The operating principle of fluid level indicators is based on a magnet connected to a float which is transmitting the level, without an additional supply power, to the glass level indicator bar consisting of magnetic rollers or flaps. To customer specifics, different magnetic switches or level sensors can be fitted as additional accessories.
