Automated Natural Gas and Crude Helium Measurement System.
NTIS: PB 90-130097 :74 pages
The U.S. 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. Helium Field Operations has a total of 24 meter runs at 3 different points along the Bureau's crude helium pipeline. This report discusses the hardware and software used to measure the different flows. The software, entirely developed by Bureau personnel, is written in easy to understand advance basic language. The program calculates an incremental gas flow every 15 min in accordance with standards presented in the publication "Orifice Metering of Natural Gas-American Gas Association Report No. 3." Each morning, a personal computer is used to calculate, record, and print the 24-h gas volumes. Bureau personnel can access current gas flow information at any time to monitor crude helium flow. Through a series of straightforward menus, personnel can also change orifice plate constants, calibrate transmitter hardware, view stored flow data, and perform other functions. The Bureau's gas measurement system can be modified for use by any company with similar requirements. The appendix documents the software for a typical crude helium measurement system.
