Knowing exactly how much media is present in a tank or how much product is in a cargo hold is essential for running a ship. The measurement is usually performed by a level instrument using methods such as radar, ultrasonic, electrical capacity, floaters (relays) or pressure. A level measurement can be used in many applications e.g. automating the loading and transfer of cargo, ballast water and fuel to their respective tanks as well as ensure the stability of the vessel via level based trim monitoring.

The Basics of Level Measurement
Level measurement is basicly measuring the quantity of a product within a vessel/tank. This could be either a soild or liquid substance like oil, chemicals or coal. The level measurement device is usually placed on the top of the vessel or the bottom/side depending on the measuring princible.
When doing a continuous level measurement a level transmitter detects the level of a medium in a tank and converts it into an electrical signal. The level signal can be displayed locally or incorporated into an on board management system.
A point level detection is a level transmitter which detects when a certain predefined level is reached. A switching command starts or stops filling equipment or similar from the sensor signal.
We offer level sensors across all the different measuring principels which includes:
- Radar
- Guided Wave Radar
- Ultrasonic
- Capacitive
- Hydrostatic
- Radiation-based
- Vibration
