Automated Natural Gas and Crude Helium Measurement System

摘要

The Bureau of Mines--Helium Field Operations has developed an automated system to fulfill its natural gas and crude helium measurement requirements. The system provides current gas flow information, automatic system calibration, daily flow volumes, and a computer-user interface. The report discusses the hardware and software used to measure the different flow. The software is written in Advance BASIC Language. The program calculates an incremental gas flow every fifteen minutes. Each morning, a personal computer is used to calculate, record, and print the 24-hour gas volumes. Bureau personnel can access current gas flow information at any time to monitor crude helium flow. Through a series of straight forward menus, personnel can also change orifice plate constants, calibrate transmitter hardware, view stored flow data, and perform other functions. The Appendix documents the software for a typical crude helium measurement system.
