- Model：
The principle of floating ball magnetic liquid level switch is equipped with an appropriate constant magnetic field in the floating ball of the pole. Due to the rise or decrease of the liquid level, the magnetic field generated inside the floating ball triggers the dry reservoir in the pole to generate action. Widely used in the field of liquid level measurement, liquid level alarm and liquid level safety control.
