Ship liquid level measurement, or tank gauging, uses various technologies to monitor the amount of fuel, ballast water, liquid cargo, and wastewater onboard, which is vital for safety, stability, and operational efficiency.

Ultrasonic Level Sensors

• Principle: Similar to radar, these sensors measure the time of flight for an ultrasonic sound wave to travel to the liquid surface and back.
  
  

• Application: Suitable for non-foaming liquids in open or closed vessels where the environment doesn't interfere with sound wave propagation.
