Observations of the Use of the Setapoint Detector.
Abstract
In a previous investigation, a variety of tests were used to study the low temperature flow behaviour of aviation turbine fuels. These included both specification fuels, and others that had higher than usual freeze points, but whose use might become necessary in the future. One procedure employed the Setapoint detector, manufactured by Stanhope Seta Ltd. This device measures the resistance to passage of a fuel pumped back and forth across a screen during a programmed cooling regime. In an attempt to find the reason for certain abnormal test results obtained using the Setapoint detector, a review of experimental results was conducted. Visual observations made during the tests were considered in conjunction with the stop flow and flow points. A number of distinct modes of behaviour, some leading to aberrant results, were identified. The instrument appeared best suited to specification aviation fuels, and middle distillates that produce fine homogeneous wax deposits during the test.
