    Tips: Float liquid level sensor troubleshooting

    Faults Reasons Solutions
    The floating ball does not work. The specific gravity of the liquid is less than the floating ball. Reconfirm the specific gravity of the floating ball.
    The floating ball is leakage. Replace the floating ball.
    Foreign matters stuck the floating ball. Remove foreign matters.
    Floating ball works but no signal output. The position of the floating ball is offset. Adjust the position of the floating ball.
    The magnetic spring switch is damaged. Replace the magnetic spring switch.
    Signal output is abnormal. There is magnetic interference nearby. Eliminate magnetic field.
    The signal cannot be restored and the floating ball cannot be returned. It got stuck by foreign matters. Remove foreign matters.
    There is two signal output at one point. Ring position moved. Adjust it.

    Existing reviews of Float Liquid Level Sensor, Stainless Steel/ Plastic
    Good experience
    The user experience of this float level sensor is quite good. When I tested in the water tank, the sensor accurately detected changes in the liquid level, responded sensitively, and there was no delay. This sensor is particularly suitable for use in water tanks or liquid storage systems, as it can effectively monitor liquid levels and ensure safe operation.

    Better than expected!
    My old float level sensor failed so I needed a replacement quickly. I bought this float switch, it was inexpensive compared to the original one, but it worked great for me. Better than expected!

    This float liquid level sensor works very well.
    This is the nicest magnetic float level sensor I’ve ever bought. I used this with a small submersible water pump. Works very well. For the price, compared to other float switches, it is very good.
