SURVEYOR Cargo Level is a complete tank measurement automatic level gauging and cargo monitoring system for tankers. The system is one of the most comprehensive and accurate systems available for this specific application. Together with advanced signal handling and computer technology, the functions included are as following:

  • Level gauging in cargo, slop, ballast, and fuel oil tanks.
  • Density measurement in cargo, slop, and fuel oil tanks
    (only with pressure sensors).
  • Vapor (inert gas) pressure in cargo and slop tanks.
  • Draft measurement.
  • Loading computer for intact stability and stress with load planning.
  • Print out of cargo and transfer reports.
  • Serial line interface for communications with other systems available.
  • High level and overfill alarm.

As all parts and functions are based on the same sensor technology, the tank monitoring system is very cost effective and operationally efficient for the users. The modular and compact design makes the SURVEYOR™ Cargo Level an attractive alternative for new building or retrofit installations. Separate ballast gauging systems or complete cargo tank systems are available for installations on board any type of vessel. SURVEYOR™ Cargo Level has been successfully installed on board chemical and oil tankers as well as product and container vessels and is recognized as a cost effective, reliable and user friendly system.

Non-contact Microwave Radar
One of the few marine microwave ullage gauges featuring a power and 4-20 mA signal on a two core cable, thus providing for simple, fast and cost effective installation for both new buildings and retrofit projects. Because of its unique design and technology there is no need for large and tall adapter trunks in order to fit radar to the deck. The system provides for automatic trim and list correction and allows exporting of level either at the flotation center of the tank, at the sensor location or at the sounding pipe.


  • High accuracy in all kinds of cargo.
  • Compact design and easy installation.
  • Superior technology allowing fitment close to the tank side also on smaller tanks.
  • For Chemical and Oil/Product tank installations a special PTFE flange seal provides a non-stick surface that eliminates cargo buildup on the radar antenna.
  • Measuring of the solids cargo level that previously could not be done accurately with radar.
