Haxella Magnetic Bi-Colour Level Indicator, The magnetic float traverse up & down inside the chamber due to rise & fall of liquid Level inside tank. A bi-colour indicator strip is externally mounted outside the chamber, which is made of a series of sealed half-red & half-white dual-colored magnetized rollers or flappers positioned horizontally at their rotating bushes. Traverse motion of magnetic float inside the chamber causes a magnetic field at that point, which in turn makes the bi-colour rollers to rotate on their axis due to reverse magnetic polarity, thus changing their colour state from white to red during liquid rising/float moving up & vice versa red to white during liquid Level falling/float moving down inside the tank.
