Liquids level monitoring is very important in several applications like water level monitoring in running water and tanks, flood monitoring, waste water monitoring and snow level monitoring.
Ultrasonic or laser type sensors can even be used to measure silos fill level.
Useful addition to level monitoring is water quality monitoring and leak detection.
