Liquid level sensors Application:


A wide range of level sensor measurement systems are made available for addressing the various parameters such as a wide range of applications, high-accuracy needs, and system installation requirements and practices. Measurement technologies are made available in different versions to address a wide range of measurement needs, or to address a specific application.


Liquid level sensors are termed as the sensors used for detecting liquid levels or interfaces between liquids such as water and oil or solids and liquids. These sensors can also be defined as transducers or as integrated systems with instrumentation and control capabilities. This type of liquid level sensor is one of the most important sensors and plays a vital role in variety of industrial and consumer applications.
