Method-Pressure Drop Tests for Fuel System Components
This document describes recommended methods, associated equipment, and test setups to assist in understanding and conducting pressure drop tests on fuel system components. Background information and suggestions are provided to improve accuracy and repeatability of test results. Although written specifically for fuel system components, the methods, equipment, and suggestions presented herein apply equally to pressure drop tests conducted on any equipment utilizing incompressible fluids.
This revision expands the scope of the original document content beyond the use of piezometer rings for the measurement of pressure in fuel system applications. Further details are provided for measurement of flow and pressure in general applications with the use of industry standard instrumentation.
