A level switch is a sensor which can be installed at the top of the tank in order to prevent the fluid from overflowing. On the other hand, it can also be used to maintain a minimum level of fluid in the tank. The liquid level is detected with the use of electrodes. There are many applications of level switches in residential, commercial, industrial and municipality sectors. These devices are available in Side Mounted, 90 Degree, Miniature, Adjustable, Magnetic Float and other types. Other than liquid, it is possible to measure the level of powder and granulated material.
