Abstract
As part of a test series to evaluate the performance of optical flame detectors, it was necessary to develop a system to determine the size of unconfined flammable liquid spill fires. A system using Ni-chrome wire was developed to directly measure the surface or horizontal flame dimension in both the "X" abd "Y" directions, assuming that the fire was oval in shape. The method is described in this report. Also discussed are the electrical circuit used for the measurements,the calibration procedures, test results and the limitations of the system.
