Magnetic water level sensor (CMW35/45/55/65)

Floating level sensors are used where constant control and adjustment of the fluid level (water, oil and other fluids) is needed. The sensor has a float mounted with a magnet that, acting by the buoyant force of the fluid, slides over the tube, causing the reed switch to close or open. They are usually mounted in the bottom or cover of a tank to control the upper and lower fluid levels.
