Computerized Automated Pressure/Volume Calibration System

摘要

An automated pressure/volume calibration system was designed and developed for application by Mound's Standards Laboratory. The system utilizes laboratory equipment to measure pressure, temperature, and vacuum precisely. The data obtained from these measurements and the value of a known standard volume are used to calculate an unknown volume for gas containment to an accuracy of approximately ± 0.3％. The process utilizes the forward-reverse substitution technique which eliminates the need for a separate determination of the plumbing volume. The technique is usable for volumes that are regular or irregular in shape, and is not limited in size restrictions as long as an adequate standard volume is available.
