Marine Fuel Density meter 

Fast and accurate testing on-site               

Parker Kittiwakes Marine Fuel Density meter is used to measure density in fuel. Fuel is delivered from the bunker barge by volume and confirmed by meter or tape soundings. It is paid for by mass with a conversion relying on an accurate density reading. The density meter provides that and more. 

Identify and confirm quality of a fuel

Along with viscosity, the density of marine fuels is one of the main parameters that can be used to identify and confirm quality of a fuel. Checking the density of a fuel prior to or at the beginning of a bunker operation, could therefor be a crucial aid in determining if the delivered fuel is according to the agreed quality and specifications.

The Marine Fuel Density Meter FG-K1-300-KW from Parker Kittiwake is a compact, cost effective and efficient tool for measuring density of all conventional marine fuel types on board. Measuring fuel oil density in kg/m3 at 50°C with its built-in heating feature, it provides a measurement with no further need for calculations or conversions.


Easy to use - Portable density meter

The equipment is designed to be used by the crew, and the test itself is completed within 10 minutesI. An immediate re-test of an already heated sample for confirmation of results, will take no more than 30 seconds. The FG-K1-300-KW performs according to ASTM D-1298 and IP160.

If it is required to measure the density of highly viscous fuels, a measurement at 70°C is also an option with this instrument. As standard, the FG-K1-300-KW also provides CCAIII, Density in vacuum and viscosity conversions.

Note: The Density meter is not suitable for use with any fuel with a low flash point temperature, and must not be used for heating any liquids other than diesel or residual fuel oils.


Main advantages and benefits: 

  • Ensure the correct weight og fuel has been delivered
  • Fast, accurate results for mulitple oil parameters
  • Make informed onsite maintenance decisions
  • Act before the onset of critical failure
  • Robust and reliable in harsh or remote enviroments
