Section III. PRINCIPLES OF OPERATION
1-11. SYSTEM TECHNICAL PRINCIPLES OF OPERATION.
a.
Technical Principle. Sampling of fuels from pressurized systems through contamination analysis monitors for
gravimetric determination of contaminant level.
b.
Principles of Operation as follows:
(1) Particulate Contaminants. A fuel sample is taken from pressurized systems with a sampler-valve hose
assembly containing monitor pads. The color of the pad is compared with the Fuel Color Standards
provided.
(2) Undissolved Water. A fuel sample is passed through Free Water Pads, then the pad is placed under ultra
violet light (Detector Unit, Free Water) and read out in parts per million water.
(3) American Petroleum Institute (API) Gravity Procedure. A fuel sample is placed in a test cylinder and a
hydrometer is inserted. The degrees API are read and the sample temperature recorded. Using the
gravity computer, the API is determined.
