Level sensors are devices used to measure and monitor the level of liquids or solids in tanks, vessels, or other containers. They play a critical role in various industries including manufacturing, water treatment, oil and gas, and more. The principle behind liquid level sensing involves detecting changes in physical properties, such as pressure, capacitance, ultrasonic or optical properties, to determine the level of a substance.
Common types of liquid level sensors include submersible level transmitters, magnetic float level switches, radar level meters, ultrasonic level sensors, etc. These sensors provide real-time liquid level measurement, enabling efficient inventory management, process control and safety monitoring. Level sensors are critical to preventing spills, optimizing storage capacity, and ensuring accurate material handling in a variety of industrial applications.
