Marine Fuel Density Meter Kittiwake
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. CCAI, Density in Vacuo, Viscosity conversion.  The Density Meter measures more than just diesel & residual bunker fuel density :
Confirm the quantity of fuel delivered, correcting volume to density
Verify that the correct grade of fuel has been delivered under ISO 8217
Estimate the combustion performance ( CCAI ) and correct viscosity in cP to cSt.
Most oils can be measured at 50°C with an option at 70°C very viscous fuels. The calculator provides Density in kg/m3 @ 15°C in a vacuo. For a known viscosity it will convert Censtistokes or  Centipoise and calculate CCAI*. Purchased as a stand-alone kit supplied in its own case or as part of a more extensive suite of testing equipment in the Fuel and Lube Oil Lab or Power Plant Lab. The Density Meter has been proven to be as accurate as laboratory methods.
