A portable, lightweight, compact contaminated fuel detector uses a standard batch sampling technique. This is done through two series filters in a filter holder into a vacuum receptacle. The differential filter opacity is checked in a photocell fixture using a light whose intensity is first adjusted by potentiometer to a standard level using a milliammeter which is also read to determine each filter opacity. The compactness and weight reduction is accomplished using a lightweight box enclosure with a supporting deck carrying equipment including a hand-operated vertically oriented vacuum pump and careful arrangement of the pump within the enclosure relative to other elements of the system.

Compact portable contaminated fuel detector with hand-operated pump

A portable compact contaminated fuel detector is used with a standard batch sampling technique. The sample is passed through two series filters in a filter holder into a vacuum receptacle. The differential filter opacity is checked in a photocell fixture using a light whose intensity is first adjusted by a potentiometer to a standard level using a milliammeter which is also read to determine each filter opacity. The operating structure is carried on a tiered deck providing different horizontal levels for greater ease and facility in performing tests. The device is combinable with a free water detector, preferably within the enclosure provided by the deck and having an auxiliary movable closure through which the test procedure may be viewed. The free water detector includes a sample holder for filter sample in close proximity to a plurality of comparison standards representative of different water content levels against which the sample may be compared. An ultraviolet light source is positioned to illuminate a filter in the sample holder and comparison standards, the light being such as to cause chemicals in the filter subject to reaction with free water in a fuel sample passed therethrough, as well as the comparison standards, to fluoresce. The intensity of the sample fluorescence is a function of the amount of free water in a sample of standard size and the intensity of the comparison standards is fixed to represent that fluorescence which occurs with known concentrations of free water in a sample of that size.
