RealFLO™ Multi-run Gas Flow Computer Software

Weatherford’s RealFLO multi-run gas flow computer (GFC) software converts any SP series controller into a full function GFC, while retaining the controller’s inherent logic programmability. The result is a versatile GFC that is well suited to a wide variety of oil and natural gas applications. Any application requiring gas flow measurement, a programmable logic controller (PLC) for local control and a remote terminal unit (RTU) for communication is a candidate for automation with RealFLO software.

The program provides AGA-3 orifice plate, VCone and AGA-7 turbine meter flow measurements with AGA-8 or NX-19 gas density calculations. In meeting the requirements of API 21.1, custody transfer, the software provides 35 days of hourly and daily averages, 700 user changes and events as well as 300 process alarms. No additional logic programming is required to use the software; it is complete and ready for configuration and use.

Software configuration is provided by an intuitive, windows-based program that executes on Windows 98/ME/NT/2000/XP operating systems. Users who wish to integrate SP series controllers into existing SCADA systems will benefit because they use Modbus® native communication protocols. Custom protocols can also be added by implementing the C and C++ toolkits.

With SP32 series PLCs for example, 10baseT Ethernet can be used for high-speed remote configuration and data collection via wireless Ethernet radios. Any human machine interface (HMI) software package, distributed control system (DCS) or SCADA master that uses Modbus protocol can be used as the front-end. Any host computer can read historical data logs and reconfigure RealFLO software through the SCADA communication system. The program integrates seamlessly into existing SCADA systems.
