High-Pressure Computerized Gas-Metering Manual for System I at Building 343

摘要

The computerized gas metering system is a high-pressure (up to 16,000 psi) gas flow test facility which can: control a metering valve to maintain a prescribed pressure profile; acquire data from various transducers, e.g., strain, pressure, temperature, etc.; display data, a plot, and the system diagram during the test; and produce post experimental plots. The computerized gas metering system can perform limited suspensions and resumptions of an experimental run. When a test is suspended, a pressure profile can be changed and when the test is restarted, it will follow this new ramp. Finally, an operator can end a test prematurely by pressing either a VENT or an ABORT key on a terminal. With the vent option, data will be saved, with the abort option, data will be purged. This manual describes the responsibilities of the high pressure facility representative interacting with an experimenter, features of the gas metering system, and the procedure for running a test.
