The FDM 6000 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 FDM 6000 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 vapor 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"
The FDM analyzer employ a Surface Acoustic Wave (SAW) vapor sensor to measure the concentration of fuel in used oil samples by sampling the “headspace” in the vial. The device assumes (based on Henry’s Law) that the fuel concentration in the headspace vapor is directly related to the fuel present in the oil sample. The surface of the SAW sensor has a polymer coating with specific solubility to fuel vapors. The sample pump draws the headspace vapor through the SAW sensor where it is absorbed onto the polymer coating and detected. The purge pump then pushes air through the SAW to clean the system so it is ready for the next sample.
