ABB Totalflow vs SCADAPack — Choosing the Right Device for Oilfield Automation
Key Takeaway
Compare ABB Totalflow XFC/XRC and Schneider Electric SCADAPack for oil and gas — flow measurement vs general-purpose RTU, protocols, programming, and custody transfer suitability.
Quick Answer
ABB Totalflow is a dedicated flow computer with built-in AGA calculations certified for custody transfer. SCADAPack is a general-purpose RTU with IEC 61131-3 programmability. Choose Totalflow for custody transfer metering; choose SCADAPack for general pipeline telemetry and complex automation. The Bristol FB300 is another RTU alternative for comparison.
Comparison
| Feature | ABB Totalflow XFC | SCADAPack 350 |
|---|---|---|
| Primary Purpose | Gas flow measurement | General-purpose RTU/PAC |
| AGA Calculations | Built-in, certified | Custom programmed |
| Custody Transfer | Approved for fiscal measurement | Not standard |
| Programming | PCCU32 registers, TAS (XRC) | Telepace Studio (IEC 61131-3) |
| DNP3 | Level 2 outstation + master | Level 2 outstation + master |
| Archives | Hourly, daily, event (built-in) | DNP3 event buffer, custom logging |
| GC Integration | Native application | Custom Modbus programming |
When to Choose
- Custody transfer metering → ABB Totalflow
- General pipeline RTU → SCADAPack or Totalflow XRC
- Complex automation + measurement → Totalflow XRC or SCADAPack
- IEC 61131-3 programming needed → SCADAPack
Frequently Asked Questions
SCADAPack can perform AGA calculations using custom IEC 61131-3 programs, but this requires significant development and is not certified for custody transfer by default. ABB Totalflow has AGA calculations built in and certified for fiscal measurement.
The XFC is a dedicated flow computer, not a PLC. The XRC adds programmable control logic making it closer to a PAC, supporting both measurement and automation.
