LEVSEN Top Mounted Displacer Operated Level Switch DLS 10 is very useful and reliable for controlling the liquid level in under ground and overhead tanks

Operation

Operation is based on a buoyancy principle where by a spring is loaded with weighted displacers which are heavier than the liquid under control. These displacers are suspended by spring with a suspension rope. Immersion of the displacer in the liquid results in a buoyancy force change, which changes the effective weight of displacers this causes the spring to retract slightly. As a result of retraction of spring, the attraction sleeve attached to spring move upwards into magnetic field of external magnet to trigger the switching action and vice-versa.
