Abstract
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.
