Liquid Level Sensor

Summary

A Liquid Level Sensor is a device used to detect and measure the level of liquids within a container, tank, or system. These sensors are widely used in industrial, automotive, medical, and household applications to monitor liquid levels, prevent overflow, and automate fluid management. They operate using different technologies, such as float, capacitive, ultrasonic, optical, and resistive methods, depending on the application and liquid type.
