A MICROSEPAROMETER (PORTABLE SEPAROMETER) USED FOR THE DETERMINATION OF WATER SEPARATION CHARACTERISTICS, FREE WATER AND PARTICULATE TESTING OF MID-DISTILLATE FUELS (JET, DIESEL, ETC). THE DEVICE DETECTS THE PRESENCE OF SURFACTANTS IN MID-DISTILLATE FUELS WHICH CAN DEGRADE FILTER SEPARATOR PERFORMANCE. THE TEST CONSISTS OF TAKING A SAMPLE OF FUEL, ADDING WATER AND GENERATING AN EMULSION. THE EMULSION IS THEN PASSED THROUGH A MINIATURE COALESCER AND IS OPTICALLY TESTED FOR CORRECT REMOVAL OF WATER. THE RESULT IS OBTAINED IN APPROXIMATELY FIVE MINUTES. THE INSTRUMENT CONSISTS OF AN ALUMINIUM ATTACHE-STYLE CASE WITH AN ELECTRONICS SECTION AND A LIFT-UP SECTION CARRYING A MECHANICAL DRIVE AND A HIGH-SPEED MIXER FOR PRODUCING AN EMULSION.
