Float, Level SensorsFloat and level sensors are sensors that are used to measure the level of a liquid in a container or tank. These sensors typically consist of a float that is connected to a lever or other mechanism, and a sensor that measures the position of the float. The position of the float is directly related to the level of the liquid in the container, and the sensor output can be used to control a valve or pump to add or remove liquid from the container. Float and level sensors are commonly used in a wide range of applications, including water treatment, industrial process control, and automotive systems. These sensors are typically small and compact, and can be easily integrated into a wide range of liquid level management systems.
