Abstract: This instruction report describes automated procedures for conducting discharge measurements in a closed conduit with facilities for shutting off the flow at a downstream location. The method described herein is a modification, developed at the U.S. Army Engineer Waterways Experiment Station (WES), of the proven Gibson (pressure-momentum) Method. The WES apparatus used in performing the tests consists of a Data Acquisition and Control System (DACS) which includes all components of the measurement, data recording, and data analysis system. The control unit and microprocessor of the system are programmed to guide the operator through the complete test. This includes calibration, data acquisition, and computations, thereby providing a complete onsite analysis. This manual outlines the step-by-step procedures involved. NOTE: Several blank pages that were intended for taking notes at the end of the print report were not scanned.
