This water level sensor works on a simple conductivity principle. It has two high-quality stainless steel rods that detect the presence of water by sensing electrical conductivity. When water touches the rods, the sensor sends a signal to the controller.

It is widely used in water level alarms, automatic water level controllers, and water level indicators. The corrosion-free stainless steel design ensures reliable performance and long service life, making it suitable for continuous use in tanks and pipelines.
