Polo Star Magnetic Float Sensor Switch for Liquid Water Level Controller | Water Tank | Pipe Mount | Top - Vertical Mount | Fit & Forget Design | 2 MTR Heavy Cable | with Reversable NO – NC Pack of 2

The device is working fine and giving me better control on overhead water tank filling

This product is very very light in weight as a result when water fills up, the entire float literally floats on water causing the sensor not to work as desired. Simple solution is to add a heavy metal washer on the top or bottom or to insert a PVC 1/2 inch pipe and use tap screw to screw down the sensor at desired height. A heavy washer if provide as part of package would be better than the cheap plastic attachment.

Quality is inferior

Good quality sensors working fine

I have almost used many sensors i.e SS sensor, Float switch, Carbon sensor... all failed coz of deposits settling in it.. But this magnetic sensor is working great so far.. If any thing happens i will get back with latest info.

I bought it for my ro tank but its not working ,worst product, waste of money

Quality of product very bad low quality plastic

The float switch stops working with in two weeks of operation
