GOFW2008 is a computer notebook designed to assist field technicians with the management of natural gas measurement facilities, including meter inspections, calibrations and orifice plate, pressure transducer or other equipment change outs. GOFW2008 can be used for orifice meters and linear meters, including turbine meters, ultrasonic meters and positive displacement meters. Calculations can be made in either US or metric units. Although the GOFW2008 user interface is oriented to field use, GOFW2008 is just as valuable in the office environment.

How GOFW2008 can help you solve problems

    GOFW2008 makes quantitative calculations of the effects of meter changes showing “As Found”, “As Left” and “Comparison” for volume, energy, monetary value and other pertinent quantities. All of this information can be automatically recorded in a “Crystal Reports” file for record-keeping purposes as well as transmission to the office environment. In addition, the original data files created in the field can be saved on the laptop and uploaded to desktop office computers which use the GOFW2008 software.

  • Field Meter Test --- Record gas meter inspections
  • Meter Changes --- Record field measurement calibration and equipment changes
  • Volume Calculator --- Calculate natural gas volumes or other variables associated with gas measurement
  • Gas Quality Calculator --- From lab analysis data calculate associated variables such as heating value in BTU/scf and gas gravity (also calculate comparisons for different input data)
  • Lost Revenue Calculator --- Calculate gas revenue loss associated with meter changes and changes in input data, such as lab analysis data
  • Report Generator --- Automatically generate reports showing “As Found”, “As Left” and “Comparison” for volume, energy, monetary value, etc.
  • Units Converter --- Convert all units from US to metric or metric to US units

GOFW2008 Key Features

Volumetric flow rate, mass flow rate, differential pressure and orifice plate sizing calculations.

Comparison between two different standards Reports that can be exported to many formats Easy to use interface.

The following standards are supported by GOFW2008: AGA Report No. 3, 1992, AGA Report No. 8, 1992 (second printing, 1994), GPA 2172, 1996, AGA Report No. 3, 1985, NX19, 1962 and AGA Report No. 8, 1985.

GOFW2008 computations have been verified against the AGA Report No. 3 and AGA Report No. 8 standards and are within the limits of uncertainty required by those standards.

Note: GOFW2008 was developed explicitly for PCs using Windows versions Vista, XP or 2000.

Why GOFW2008 was developed

In 1996, Union Oil Company of California requested that SAI develop a product using the Microsoft Windows operating system which could be used by Unocal field technicians to manage natural gas measurement facilities, with an emphasis on knowing the differences between the As Found and As Left meter conditions and the effect on calculated quantities such as volume, energy, and monetary value.

In the period 1996-2000, a team led by Juan Luongo, then SAI President, developed CO$TFLOW, a predecessor of GOFW2008. Unocal personnel involved included Myron Goforth and Steve Baldwin, gas plant and metering specialists with extensive field experience. Prior to the purchase of Unocal by Chevron, CO$TFLOW was used extensively in Unocal gas measurement short courses organized by the John Campbell Co. and taught by Ken Starling, SAI founder, at Unocal locations in both the US and Thailand.
