Level Switches

Level switches, also sometimes called level control switches, are measuring utilities that indicate material levels in storage enclosures or transmission equipment; in some cases they can be used both for level measurement and level control. A level switch indicates these levels by means of an electrical switching action. Some of these devices could also be classified as level sensors or level indicators; those terms are restricted to systems that measure levels but do not control them.
