Level control systems are used to maintain the desired level of liquids or solids in various applications, such as tanks, silos, and reservoirs. These systems utilize sensors to measure the current level and automatically adjust inputs or outputs, ensuring that the level remains within specified limits. Common components of level control systems include level sensors, controllers, and actuators. The sensors detect the level, while the controller processes this information and sends signals to the actuator, which adjusts the flow of material. This automation helps improve efficiency and safety in industrial processes.
