FDM Q6000
Portable Fuel Dilution Meter

The Q6000 FDM is a portable, battery operated fuel dilution meter that determines the concentration of fuel dilution present in an oil sample within a matter of minutes. The Q6000 FDM uses a unique patent pending fang design to pierce the cap of a disposable sample vial and draws in the headspace from the vial. The headspace flows over a SAW (Surface Acoustic Wave) sensor which reacts specifically to the presence of fuel vapour with a detection range of 0 – 15%. It can detect diesel, gasoline or jet fuel in engine oil. It conforms to ASTM D8004 - "Standard Test Method for Fuel Dilution of In-Service Lubricants Using Surface Acoustic Wave Sensing".

When fuel contamination comes in contact with the SAW sensor surface it will absorb into the polymer coating. This absorption into the polymer causes a mass change which produces a corresponding change in the amplitude and velocity of the surface wave. When used in a self-resonant oscillator circuit, the change in Rayleigh wave velocity resulting from vapor absorption into the polymer coating causes a corresponding change in oscillator frequency. This change in frequency is the basis of detection.

The FDM uses one point user calibration to calibrate the system to specific fuel/oil matrix and environmental temperature. Since fuel vapor concentration varies with environmental and sample temperature it is recommended that the FDM is calibrated with a reference sample when room temperature varies by a few degrees. It is always the best practice to calibrate the FDM at the same room temperature when the samples are run.

The reference can be standard oil with known fuel dilution purchased from Spectro Scientific, or a sample mixed up with known concentration of fuel by user. Calibration can be stored for future use.
