The ABB Totalflow ® XFC G5 flow computer is extremely accurate and reliable with the capability to
measure and monitor gas flow in accordance with AGA, API, and ISO standards.
What are the typical scenarios other than custody transfer?
The table below lists the six XFC
G5 models available. They are engineered to be flexible and enable
increased productivity and improved asset utilization. These different models provide different
enclosure size options for small- to large-scale implementations and space for additional equipment
and expansion of I/O capability.
All models support single or multi-tube capability (single or multiple wells) with custody transfer
measurement features. The XFC
G5 integrates a multivariable sensor for a single tube. Additional tubes
require the connection of external multivariable transmitters, but the Totalflow application suite allows
the activation of additional tube applications as needed.
By default, the XFC
G5 stores daily and log period records over a 40-day period and logs 200 events.
These defaults can be extended and are limited only by the file space on the device.
Two versions of the integrated multi-variable sensor (XIMV) are available: one with differential
pressure, static pressure, and temperature for DP measurement applications, and one with static
pressure and temperature for linear measurement applications.

1.2.3 XRC G5 functionality
The ABB Totalflow ® XRC G5 remote controller is a highly customizable device which can be used in a
wide range of applications: control automation, monitor, alarming and measurement applications. The
device is optimized for use in oil and gas production, transmission, and distribution, site monitoring
and control, but can also have application in water and waste system and monitoring, etc.
Four XRC
G5 models are available: 6490, 6790, 6890 and 6990. They are engineered to be flexible and
enable increased productivity and improved asset utilization. These different models provide different
enclosure size options for small- to large-scale implementations and space for additional equipment
and expansion of I/O capability.
In addition to the default Totalflow applications, the XRC
G5 is the ideal system for custom
programming of advanced control or shutdown logic. Custom programming is supported with IEC
61131 applications.
IMPORTANT NOTE: XSeries G5 devices support several IEC application types. ABB-built IEC
applications are available off-the-shelf or can be designed upon request. Customer-built IEC
applications (developed by the customer or other third-party IEC programmers) are also
supported. All IEC applications must be properly licensed. Required license credits depend
on IEC application type.
