Float sensors are devices used to detect the level of liquids in tanks or containers. They work by using a floating object that rises and falls with the liquid level. When the float reaches a certain height, it activates a switch, signaling that the liquid has reached a specific level. This helps in monitoring and controlling liquid levels in various applications, such as in water tanks, fuel tanks, and industrial processes. These sensors can be mechanical or electronic. Mechanical float sensors often use a simple lever mechanism, while electronic float sensors may use magnetic or capacitive technology. Both types are essential for ensuring safety and efficiency in systems that rely on liquid management, such as aquariums, heating systems, and irrigation systems.
