Used to measure a fluid inside a container or a fluid in its natural form

Used to detect the level of liquids that flow, a liquid level sensor can measure a fluid inside a container or a fluid in its natural form.The level measurement can be either continuous or point values. Continuous level sensors measure liquid levels within a specified range and determine the exact amount of substance in a certain place. Point-level sensors indicate whether the substance is above or below the sensing point.Liquid level sensor types include: fuel, oil, bio-fuel, water, specialist, and capacitive. These sensors are utilized for liquid level measurements in marine, chemical processing, pharmaceuticals, food processing, waste treatment, automotive, and military applications.
