The magnetic float level gauge has a magnetic float inside it, which is developed based on the buoyancy principle and magnetic coupling (magnetic force of the magnetic float). When the liquid level in the tested container rises and falls, the magnetic float in the body tube of the liquid level gauge also rises and falls. The permanent magnet in the float passes through the magnetic coupling to the magnetic column indicator and drives the red and white columns to flip 180 °, when the liquid level rises, the column turns from white to red. When the liquid level drops, the column turns from red to white. The red-white junction of the indicator is the actual height of the liquid level in the container, thus achieving a clear liquid level. Instructions.
Therefore, there are three reasons why the magnetic float level gauge does not turn: (1) The float loses its magnetism, probably because of the high temperature or the float itself does not use high temperature magnetism. (2) Inside the buoy tube containing floats, there are a large number of impurities or mixed liquids with extremely high viscosity. The buoys are stuck and cannot fluctuate with the liquid level. (3) The small cylindrical body in the flap indicator has malfunctioned.
The above-mentioned reasons are prone to the second case. At this point, as soon as the drain valve below the buoy tube is opened, the internal plugging fault can be released immediately.
