Although "WARNING" hazards are related to personal injury and "NOTICE" hazards are associated with equipment or property
damage, it must be understood that under certain operating conditions, operating damaged equipment can result in degraded
system / process performance leading to serious or life-threatening injuries. Therefore, compliance with all "WARNING" or
"NOTICE" hazards is required at all times.
Only qualified and authorized specialists are to be employed for the assembly, electrical connection, commissioning, and
maintenance of the transmitter, since they have the appropriate experience and the necessary qualifications for such work, e.g.:
—Training, instruction, and authorization to operate and maintain devices or systems according to safety engineering
standards for electrical circuits, high pressures, and corrosive media
—Training or instruction in accordance with safety engineering standards regarding the maintenance and use of adequate
safety systems
WARNING –Bodily injury. For electrical connections, use sufficiently insulated tools, according to the EN 60900
standard.
Follow the applicable standards, regulations, and recommendations for installation, including:
—The construction and operation of electrical installations. For example, the regulation for technical working materials (safety
guidelines for tools)
—Explosion protection, if transmitters with explosion protection are installed
The device can be operated at high levels of pressure and with corrosive media. Serious injury and/or considerable material
damage can result if the transmitter is handled incorrectly. Ensure compliance with the regulations applicable in the country of
use when working with transmitters.
1.3 Potential safety hazards
Pressurized natural gas is present in the measurement pipeline. Because of this, a possibility exists for natural gas to escape
from the pipeline or tubing during installation or calibration, or following damage to the pipeline or tubing. Only properly trained
and authorized personnel should work in hazardous locations.
Totalflow equipment operates on 9 - 30 Vdc. However, optional equipment may convert power from Vac to Vdc. Follow your
company’s policies and procedures when installing any electrical and/or measurement equipment.
Always wear Personal Protective Equipment (PPE) per your company’s policies and procedures.

3 System Description
3.1 Overview
This chapter serves as an introduction to the Totalflow Fourth Generation Flow Computers (XFCG4). The XSeries are low power,
microprocessor-based units designed to meet a wide range of measurement, automation, monitor, control and alarm
applications for remote oil and gas systems. Six models of the XSeries are available: Models XFCG4 6410, XFCG4 6413 and
XFCG4 6713 are differential (orifice) meters. Models XFCG4 6411, XFCG4 6414 and XFCG4 6714 are pulse (linear) meters.
The letters XFC stand for Expandable Flow Computer. As the name implies, the flow computers are expandable to meet a wide
range of user needs while maintaining backward compatibility with legacy Totalflow systems.
For users that are familiar with the XSeries flow computers, the XFCG4 offers easily recognizable features while expanding on its
core functionality. This expansion includes a new CPU engine card and the adoption of 32-bit technology to enhance speed and
memory. Additionally, the XFCG4 is able to run more applications than previous XSeries units with more AGA tube applications
and more Plunger Lift applications.
For connectivity purposes, the XFCG4 supports the familiar military connector (serial communication) PCCU cable. Additionally,
USB and Ethernet connectivity are also available. The only other visual difference is the addition of an SD Card slot, the SD
card slot is not used.
3.1.1 Hardware
The models XFCG4 6410 and XFCG4 6411 are packaged in a small enclosure and are only designed for the XFCG4 board and a
variety of batteries. When using these flow computers, communication devices can be installed in a separate enclosure such as
the model 6470.
The models XFCG4 6413 and XFCG4 6414 are packaged in an enclosure that can accommodate the XFCG4 board, a variety of
remote communications devices, batteries and up to three additional I/O modules. The I/O modules generally provide eight I/O
points per module.
The models XFCG4 6713 and XFCG4 6714 are packaged in an enclosure that can accommodate the XFCG4 board, a variety of
remote communications options, batteries and up to six additional I/O modules.
3.1.2 Functionality
The XFCG4 system has built-in, pre-engineered applications for data collection, trending and long term data storage. The XFCG4
can be used for oil and gas production, transmission and distribution site monitoring and control, water and waste system
monitoring and control, etc.
All of the XSeries feature single or multi-tube capabilities with custody transfer measurement features. These flow computers
are engineered to be flexible and will enable the user to increase productivity and improve asset utilization (see Table 1 for the
XSeries family genealogy).
The XFCG4 defaults to the retention of daily and log period records over a 40 day period. Additionally, it defaults to the retention
of 200 events. These defaults can be extended and are limited only by the file space on the device.
Models XFCG4 6410/11 perform these basic functions and include additional I/O, as provided on the main electronic board
(XFCG4).
Models XFCG4 6413/14 perform these same basic functions and have the option for three TFIO modules.ds
Models XFCG4 6713/14 perform these same basic functions and have the option for six TFIO modules.
IMPORTANT NOTE: The XFCG4 maintains a history of alarms as well as average differential pressure (DP),
average static pressure (SP), average flowing temperature (Tf), accumulated volume and energy.
For the differential meters, an average extension is maintained. For pulse (linear) meters, an uncorrected
volume accumulator is maintained.
The differential (orifice) flow computer can be programmed to calculate flow rates and volumes in accordance
with either AGA-3-85, AGA-3-92 or additional flow calculations methods that are available on request. These
include ISO-5167, Liquid, Vcone, FloNozzle, etc.

16 XFC G4 2103335 Rev AB
The linear (pulse) flow computer can be programmed to calculate flow rates and volumes in accordance with
AGA-7.
Super compressibility calculations can be performed in accordance with either NX-19 or AGA 8-92 (gross or
detail).

Differential Flow Computer

17 XFC G4 2103335 Rev AB
Linear Flow Computer
3.2 XSeriesG4 Flow Computer Hardware
All of the Totalflow XFCG4 models are housed in a lightweight, two-compartment aluminum case. With the exception of the size
of the cases, the XSeries models use identical components:
—Enclosure
—XFCG4 Board
—External Integral Multi-Variable (XIMV) (6410, 6413, 6713 only)
—Battery Compartment
—Communication Compartments (6413, 6414, 6713 and 6714 only)
—Liquid Crystal Display (LCD)
—Charger or Solar Panel
—Resistive Temperature Detector (RTD)
—Optional Modular I/O
—Optional Keypad
3.2.1 XFCG4 Board
The XFCG4 board is mounted on the inside of the door. All XFCG4 input and output connections are made with Phoenix-style
snap-in connector terminals mounted directly on the board. Other circuitry processes the inputs from the External Integral
Multivariable (XIMV) and provides interfaces to the Liquid Crystal Display (LCD) and the PCCU. Remote communications are
handled by the RS-232 and RS-485 communication modules that plug directly into the XFCG4 board. The XFCG4 board offers the
following input and output points:
—XIMV Communication
—2 Digital or 2 High Speed Pulse Inputs (Selectable De-bounce Enable/Disable)
—2 Digital Outputs
—2 Analog Inputs
—2 Remote Communication Ports (RS-232 or RS-485)
—I/O Interface for TFIO Interface Modules
3.2.2 CPU Engine Card
The CPU engine card plugs into the XFCG4 board. All processor and memory components reside on the CPU engine card. The
engine card uses a low power processor running at 192MHz with 16M SRAM, 32M Flash and 256 bytes of serial EEPROM. A
lithium backup battery is located on the main circuit board. Application programs and configuration files are stored in non-volatile
Flash.
Caution- Loss of data: Unplugging the engine card disconnects it from the lithium cell backup, and SRAM
(historical flow data) is cleared.
3.2.3 Communication Compartment
A removable communications enclosure can be provided that has been pre-drilled for mounting of many popular
communications devices such as radios, cellular phones, modems, etc. Models XFCG4 6413 and 6414 provide an enclosure to
house a remote communication device, transceiver, cellular phone, etc.
3.2.4 Battery Compartment
The battery compartment houses the various optional battery packs that are available for the XFCG4. These range from eight (8)
ampere hours up to 26 ampere hours. Installation of the battery requires removing the battery plate, placing the battery in place
and connecting the battery cable to the circuit board, see section 5 Maintenance, page 89.

3.2.5 Solar Panel
The flow computercan be configured for a 10-Watt, 20-Watt or 30-Watt solar panel. The panel is designed to be mounted on a
2-inch extension pipe above the flow computer, on top of or to the side of a meter house.
3.2.6 Resistive Temperature Detector (RTD)
An optional 100Ωplatinum RTD measures the real-time flowing temperature of the gas. The standard RTD is provided with a
10-foot cable. Other lengths of cable are available upon request.
3.2.7 Additional Features
Additional features of the Totalflow system that enhance its flexibility include:
—Programmable bi-level security system prevents unauthorized communication and configuration of the flow computer.
—Internal crystal-controlled clock provides a highly stable time base for the system.
—Optional battery packs extend operation for longer periods without power.
—Three available charging sources:
–External solar panel (standard)
–External ac power
–External 24/12Vdc power
—LCD-programmable to allow monitoring of operations (for example, displays flow rate, volumes, etc.).
—Rugged, aluminum, powder-coated NEMA 4X enclosure. Lockable to prevent internal access.
—Optional ability to allow rapid data collection over several communication links.
—Additional I/O for valve control, pressure, level monitoring, remote communication, etc.
—Optional keypad.
3.3 Standard Enclosures
The standard enclosure consists of a hinged-door box in varying sizes for the XFCG4 devices (see Figure 1 through Figure 6).
The door provides a watertight, corrosion-resistant seal between the outside elements and the flow computer components. It is
designed to meet Class I, Division 2, Groups C and D and is NEMA 4X rated. It is designed for mounting in harsh environments
(cold, hot, wet and salty). Opening the door latches allows access to electronics, battery, radio, XIMV and modular components.
This door may be locked for security purposes.
