How to troubleshoot a malfunctioning float level switch

The switch structure of the float level controller is mainly designed and produced based on the principles of buoyancy and static magnetic fields. The float (referred to as a float) with a magnet is positioned in the measured medium under the influence of buoyancy. In the operating environment, changes in the liquid level result in changes in the position of the magnetic float. Interaction between the magnet in the float and the sensor (magnetic reed switch) generates a switch signal to start or stop the pump. Similar to the float level gauge principle, the float level gauge outputs a continuous signal, while the float level controller outputs discrete switch signals.
