ControlWave® GFC Plus
Gas Flow Computer
Featuring the “Express” Electronics Platform
When requirements call for an integrated, “all in
one box” chart replacement or flow computer, the
ControlWave GFC Plus from Emerson Process
Management is a cost effective, competitive solution.
Unlike chart replacements, ControlWave GFC Plus
is also able to meets users’ automation needs and
easily supervises a two-run metering and regulating
station or plunger lift operations at a well site.
32-bit ARM9 platform is capable of multiple flow
computing and process automation operations.
Smart, gauge pressure or DP/P sensor
assembly can be removed and replaced,
independently of the “top end” electronics.
Precision RTD interface provides very accurate
Very low power consumption minimizes costs
of solar/battery power systems, which are also
integrated in the package.
Three serial communication ports are standard.
Standard I/O includes 2 DI/PI.
Optional I/O expansion includes 2 DI/DO, 4 DI,
2 DO, 2 High-speed Counter Inputs, 3 AI and 1
ControlWave GFC Plus is pre-programmed
to meet API 21.1 requirements for a two-run
metering station with networking via BSAP or
PC web style menu pages are pre-configured
for all user operations
Using our ControlWave Designer, IEC 611313 programming environment, any user or third
party can modify the standard application or
create a completely customized program—and
full support from Emerson is available, every
step of the way.
Integral LCD with optional, 25-key keypad
allows operators to view and change
configurable parameters, on site, without
packing a PC.
Broad selection of modem and wireless
communications are instrument package
Remote Automation Solutions
ControlWave GFC Plus comes in a highly integrated package that includes a smart P/T or
DP/P/T (shown) sensor assembly, battery/solar power system and a broad selection of modem and radio communications options.

Additional, standard application programs will
be introduced on a continual basis.
TeleFlow users will appreciate the compatibility
of ControlWave GFC Plus in networking and
software solutions for SCADA and EFM data
editing/management, as well as the similarity in
all operations.
ControlWave GFC Plus is appropriate to all applications for “chart replacements” and flow computers,
particularly including those that require process
control or extension to two meter runs, for example:
Production wells
Injection wells
Production optimization applications
Off-shore platforms
Separation plants
Compressor stations
Storage facilities
Transmission metering stations
Distribution/LDC metering/gate stations
Use of the larger “Plus” enclosure, which accommodates a 33 AH lead acid cell battery and “snap
track” options, distinguishes ControlWave GFC Plus
from ControlWave GFC.
The larger battery, used in conjunction with either
a 30-watt or 40-watt solar panel, allows radios to
be operated on fast duty cycle. Since ControlWave
GFC uses the smaller, 7 AH battery, slow duty cycle
radio operation, only, is recommended for that
The larger battery in ControlWave GFC Plus also
provides extra capacity for I/O and is recommended
if loop power is to be sourced, internally.
Remote Automation Solutions
ControlWave GFC Plus
Finally, the “Plus” enclosure provides up to four,
snap track slots for options such as the Power
Distribution Board, 24 Vdc Loop Power Supply and
Relay Output Board. ControlWave GFC allows only
one such option, which is mounted in the door.
The difference between these two products is that
ControlWave EFM uses a ControlWave Micro RTU
platform while ControlWave GFC Plus uses a
ControlWave Express RTU platform.
Choose ControlWave EFM instead of ControlWave
GFC Plus if the application requires communication
ports and/or I/O that are beyond those provided by
the ControlWave Express Platform.
ControlWave GFC Plus is delivered in a rugged,
fiberglass enclosure that has provisions for not only
the electronics but also a display/keypad, smart
DP/P/T transducer assembly, battery/solar power
system and a broad selection of modem and radio
communications options.

Bristol’s DP/P Multivariable (MVT) Sensor Assembly
Most two-run systems use the integrated sensor
assembly for the first run and an external, smart
multivariable transmitter, such as the Bristol 3808
MVT (which includes the exact same sensor assembly), for the second meter run.
If the sensor assembly requires a repair, the user
can change it out and continue operating with the
electronics, including flow information, alarms and
historical archives, all intact.
Emerson recommends that users practice “depot
level” service, in other words, that the sensor assembly be removed and replaced at the shop rather
than out at the site.
Each sensor assembly has a nine-digit part number,
which can be used to specify a replacement part
(a listing is included at the end of this product data

For a multivariable sensor assembly, you can specify whether the static pressure sensor is oriented
to the right or to the left from the point-of-view of a
user looking at the front of the ControlWave GFC
Plus. Following the AGA3-1992 convention, we
refer to the static pressure sensor location as the
“upstream” (a.k.a. “high side”) location.
Selection “E” specifies the housing, for which there
is currently one choice, and the liquid crystal display
(LCD) and keypad.
One of two LCD/Keypad configurations can be
selected: 4 line x 20 character LCD with either a
two-button or 25-button keypad. Both display/keypad assemblies have the same “footprint” on the

Communication Port Configuration for the Standard
Application Program
COM1 – Local RS 232 port for configuration via a
PC. Flash configuration is BSAP Slave, 115.2K
baud rate. The PC port connector, that is accessible, externally, on the bottom of the front door, is
connected to this port on the CPU.
COM2 – RS 232 Network port with Flash configuration of BSAP Slave, 9600 baud. The standard
application program is compatible with an external
communication device (via RS 232) or standard
model radio. If a standard model radio is included,
the model will also include a cable that connects
this port, on the CPU, to the RS 232 port on the
COM3 – RS 485 port with Flash configuration of
BSAP Master at 9600 baud. The standard application program assumes that 3808 MVT smart
multivariable transmitters for meter run measurement are to be interfaced to this port.
The standard application program also supports a
chromatograph but a Flash Configuration change
is required to allow the chromatograph to be interfaced to COM3.
You can specify the solar/battery power system.
For most applications, the 12V, 33 Ampere-hour
(AH) battery, that is internal to the housing, can be
matched with either a 30-watt or 40-watt, 2” mastmounting solar panel.
In addition, a lithium battery pack can be specified.
This 7.2V, 35 AH, non-rechargeable battery pack
is used to back-up the primary power system. The
primary power system is either the internal, 12V, 33
AH battery or an external power source.
Note that the lithium battery won’t provide power
sufficient to operate devices, such as radios, that
require 12V nominal power. If the primary power
source fails, the lithium battery will be sufficient to
Remote Automation Solutions
ControlWave GFC Plus
operate the electronics for an extensive time—normally plenty of time to repair the primary power
For power loading details, please refer to the Bristol
product data sheet entitled, “ControlWave GFC
Power System Sizing.”
Note that system sizing “red flags,” which may tell
the user to specify a larger, external power source,
include multiple analog loops that operate from the
24V dc/dc power supply rather than 12V and operation of a standard model radio with power constantly
on rather than duty cycling.
The 40 watt panel may need to be selected for
locations that receive less than 2 sun-hours per day.
Again, the Power System Sizing data sheet provides further information.
A charge regulator is always included with the solar
panel and must be installed inside a compartment
on the back of the panel.
If external dc power is available and the user prefers that, exclusively, the “none” selection is appropriate.
A peculiarity in selection of the power system is that
the BP solar panels are FM approved for operation
in Class I, Division 2 areas while the ControlWave
GFC Plus, including the internal battery, is approved
for the same by UL.
Therefore, a UL-approved model is ordered by
specifying the battery but without the solar panel.
The solar panel is then specified by part number.

Class I, Division 2 certification can be specified.
ControlWave GFC Plus is approved by UL as an instrument. Note that this certification strictly prohibits installation of any other hardware, not indicated
by the model number, in the instrument enclosure.
Wiring to and from the I/O, communication and
power connections inside the enclosure, per the
ControlWave GFC Plus manual, are, of course, allowed.
Remote Automation Solutions
ControlWave GFC Plus
You can choose a bendable RTD that is attached
to the ControlWave GFC Plus via an armored cable
of 6-foot, 15-foot or 25-foot length. The individual
wires attach to a terminal block on the Processor/
Main Electronics board. The terminal block accepts
up to three wires.
Normally, this RTD would be used to provide the
process temperature input but the standard application program also allows the user to select an
external temperature transmitter, instead.
The bendable RTD is a “one size fits all” solution
that is perfect for most applications and excellent for
depot-level inventory situations in which the ultimate
installation (and, therefore, thermowell depth) is not
necessarily known.
The 12” probe can quickly be inserted in a
thermowell, whereupon the user can tighten the included fitting to lock it in place and bend the excess
length out of the way. Note that a thermowell is
required for this bendable RTD!

RTD Interface Information
A three-wire platinum RTD per DIN 43760 is supported. The temperature, T, in degrees Celsius is
calculated using the Resistance vs. Temperature
Tables according to the DIN EN 60751 standard
for Class A & B RTDs. ControlWave GFC Plus
supports the full range in the DIN standard, -40 to
For new installations, or those lacking a thermowell,
you can choose one of three lengths of thermowell
for the RTD.
The DIN EN 60751 equation is:
R(t) = R0 * (1 + At +Bt2)
A = 3.9083 * 10-3 oC-1
B = -5.775 * 10-7 oC-2
Ro = 100ohms
In addition, the user may enter the Ro, A, and B
coefficients of a custom calibrated RTD, another
platinum standard or a different material (Nickel,
Balco or Copper).
During the RTD calibration, the user will be able to
set the coefficients, restore the factory default for
these coefficients, and calibrate the internal Reference resistor.
RTD Input Specifications
Since the I/O card does not include loop power, this
option provides power if 4 – 20 mA loops are to be
used or if transmitters that require a voltage higher
than the nominal, 12 Vdc supply voltage are to be
powered. This option converts the nominal, 12 Vdc
input to 21.4 Vdc for field devices such as transmitters.
Please note that, since the minimum input voltage
for this option is 10.8 Vdc, it will not work with nominal 6 Vdc or 9 Vdc power sources. While the 21V
dc/dc Power Supply is required for use with a Bristol
3508 transmitter, it is not necessary to provide
power to 2808 or 3808 MVT models.
For those, we recommend that system power be
routed to the transmitter. The Power Distribution
Board is a good way to provide power routing to
either of those transmitters. Furthermore, the 2808
and 3808 MVT will operate using nominal 6 Vdc and
9 Vdc power sources.
The 21V dc/dc Power Supply is not necessary if
loop power is otherwise available or if there are no
analog I/O points.
These specifications are for the interface, only, not
including the RTD probe or wiring (please note that
RTD probe interchangeability can add ±0.7°C of
uncertainty to the measurement).
This option is a circuit board that is located on a
Snap Track, which is installed onto the back panel
in the lower, right-hand section of the enclosure.
RTD Conversion Accuracy: ± 0.1°C, or ± 0.1%
of reading, whichever is greater
Ambient temperature effect on RTD
measurement: ±0.01°C / ºC max
Note that the Power Distribution Board is also
required if the 21V dc/dc Power Supply is selected.
This is another Snap Track option that is located
nearby the 21V dc/dc Power Supply.
Long Term Stability at Constant Conditions:
±0.25ºC / month max

chassis. You can choose the minimum I/O configuration of 2 DI/DO, 4 DI, 2 DO and 2 HSC/DI or an
expanded version, which additionally includes 3 AI
or 3 AI and 1 AO point.
Frequency Range: 0-10 kHz
Debounce: None
Accumulator: 16 bit
What is the difference between a “PI” (pulse input) and “HSC” (high-speed counter input)? The
HSC circuitry includes de-bounce, which is useful
with form ‘C’ relays, such as those in some pulser
devices. A PI does not include the de-bounce
circuitry and is, therefore, not recommended with
relays. Note that, in the HSC inputs, the de-bounce
can be enabled/disabled by the user and they are
shipped disabled.
Number of points: 4 DI-only and 2 points that
are selectable as inputs or outputs;
Input configuration: Dry contact
Input filtering: 15 milliseconds
Input current for DI points 1 – 4 (those that are
DI-only): configurable as 60 uA for low power
applications or 2 mA nominal at 3.3V per input
We recommend that users select the 3 AI / 1 AO
configuration if use of analog I/O is anticipated in
the future because addition of the points requires a
change-out of the I/O card—due to hazardous area
certification requirements, that can be done only at
the factory.
Input current for DI points 5 – 6 (those that are
selectable as DI or DO): configurable as 200 uA
for low power applications or 2.2 mA nominal at
3.3V per input
On state: >1.6 V, Off state <1.3V

In addition to the basic functions and function
blocks, ControlWave Designer brings the benefit
of many years experience in measurement and
SCADA to Emerson’s ACCOL III function block
library. ACCOL III includes over sixty function blocks
that are valuable for use in oil & gas and process
measurement & control applications. Further, ACCOL III is designed to take full advantage of the
significant features offered by ControlWave.
Briefly, this library includes function blocks for:
AGA gas flow and API liquids calculations
Audit, Archive, File Handling
Average, Compare, Totalize
Scheduling & Sequencing
PID & Lead/Lag
In addition, ControlWave ensures data integrity, in
the event of a communication interruption, by storing critical time-stamped alarm and historical data
in the controller memory. This data is then securely
retrieved when communication is restored.
