GOFW2015 is a computer notebook designed to assist field technicians with the management of natural gas measurement facilities.


GOFIntranet2015 is a powerful calculation dll developed by Starling Associates to create in-house custom natural gas properties and flow calculation applications on your company intranet. Principal uses of GOFIntranet2015 include calculations of natural gas properties and natural gas flowrates using orifice meters (both flange and pipe taps).  Calculations of gas flowrates for linear meters also can be performed.


GasProps2008 accurately calculates 21 natural gas properties using equations in the gas industry standards AGA Report No. 8 and AGA Report No. 10.


C6PlusHCDPmatch software provides accurate calculations of natural gas dew points in pipelines. With C6PlusHCDPmatch the gas analysis is  extended mathematically so the Peng-Robinson equation of state will match the single measured dew point taken from a typical gas chromatographic analysis coupled with a dew point temperature measurement at pipeline pressure.



GOFXLV5 is the latest edition to SAI's most popular product line in the SAI Natural Gas Measurement Suite among customers who need or prefer to utilize spreadsheets in their work.


GOFXL2015 is the most popular product in the SAI Natural Gas Measurement Suite among customers who need or prefer to utilize spreadsheets in their work.


GOFLIBC2015 is a complete library of C functions created to perform flowrate calculations for measurements with orifice meters following the standards in AGA 3.3 (2013), AGA 8 (1994 Reprint), and AGA 3 (1992).  SAI can work directly with customers to modify the code to their needs.  For example, the software currently does not cover AGA 7 (1996, turbine meters) or GPA 2172 (2009, 1996), but these standards can be added based on customer needs.


Using the natural gas composition, PRDewPointCurveXL2017 calculates the natural gas hydrocarbon dew point (HCDP) curve in a Microsoft Excel spreadsheet.


PREnvelopeAndLiquidXL software provides accurate calculations of hydrocarbon mixture phase envelopes and liquid drop out within the phase envelopes.
