that has provisions for not only the electronics but also a
display/keypad, DP/P/T transducer assembly, battery/solar
power system, and a broad selection of modem and radio
communications options.
CWGFC
June 2012
Item Descriptions and Specifications
Standard equipment includes Lexan housing with 2-line
LCD, single board electronics assembly, and the standard
API 21.1 flow measurement application program. Standard
I/O count is 2 DI/PI (Pulse Inputs). Also included in the base
product are interfaces to Emerson’s gauge pressure or
multivariable, DP/P sensor assembly, an RTD interface, AUX
power output (e.g. to switch power to a radio), and shunt
regulator for solar panel charging of an internal lead acid cell
battery.
Most two-run systems use the integrated sensor assembly
for the first run and an external, smart multivariable
transmitter, such as the 3808 MVT (which includes the exact
same sensor assembly), for the second meter run.
If the sensor assembly requires a repair, you can change it
out and continue operating with the electronics, including
flow information, alarms and historical archives, all intact.
Emerson recommends that you practice “depot level”
service. In other words, the sensor assembly is removed and
replaced at the shop rather than out at the site.
You can also specify all of the following:

Integral gauge pressure or multivariable (MVT) DP/P
sensor assembly, and upper range limits

Bendable RTD assembly, pre-wired

Thermowell

A two-line LCD with no pushbuttons, two-line LCD with
two pushbuttons, or a four-line LCD with 25-key keypad

I/O card, including 2 DI/DO, 4 DI, 2 DO and 2 HSC/DI
and, optionally, an additional 3 AI, 1 AO

Hazardous area approval — Class I, Division 2

Choice of integral, battery, and solar power systems

Choice of standard model modem or radio that is
installed on an internal bracket. Standard radios are
those that are commonly available from Freewave and
MDS.

Polyphaser surge suppressor for the radio
Each sensor assembly has a nine-digit part number, which
can be used to specify a replacement part.

can be defined. The ControlWave GFC can be set to
automatically sequence through this list.
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. Following the AGA3-1992
convention, we refer to the static pressure sensor location
as the “upstream” (a.k.a. “high side”) location.
Integral Enclosure and LCD/Keypad

and additionally allows the operator to view and modify
ControlWave GFC inputs, process variables, calculated
variables, setpoints, tuning parameters, and outputs used in
a measurement or control application. Status bits include
the alarm state, alarm acknowledge, control, and manual
(Auto/Man). Providing access to such variable information
allows you to have complete control over the process
operation.
Mounting Hardware
You can specify optional hardware for pole-mounting or
wall-mounting. The “pole-mount” kit includes two wallmounting plates and two pipe clamps.
Without the mounting hardware, the ControlWave GFC is
suitable for process-mounting to a direct-mount manifold.
Note that this is appropriate only for models with MVT
sensor assemblies. A unit with a gauge pressure sensor
should not be process-mounted.
Processor/Main Electronics
The processor electronics assembly consists of a single
circuit board, which is installed on the far left-hand side in
the enclosure.

Audit Trail Alarm and Event Storage
ControlWave GFC keeps an Audit Trail Buffer capable of
storing the most recent 500 Alarms and the most
recent 500 Events. Internally, these buffers are
maintained separately to prevent recurring alarms from
overwriting configuration audit data. Externally, they
are reported to the user as a single entity. Both operate
in a circular fashion with new entries overwriting the
oldest entry when the buffer is full. The following
circumstances cause an entry to be made in the Audit
Trail Buffer:

or external transmitters.

Self Diagnostics
ControlWave GFC periodically runs a series of
diagnostics to verify the operational status of various
system components. The tests include transducer
parameters, main and backup battery voltages,
software sanity checks, and other indications of system
health. An appropriate alarm is generated if any test
fails.
Communication Port Configuration
for the Standard Application
Program
COM1 — See Specifications in the Table on page 8. The external
PC port connector, accessible on the bottom of the front
door, is connected to this port on the CPU.
COM2 — See Specifications in the Table on page 8. 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 radio.
COM3 — See Specifications in the Table on page 8. The
standard application program assumes that 3808 MVT
multivariable transmitters for meter run measurement are
to be interfaced to this port.
www.EmersonProcess.com/Remote
June 2012
The standard application program supports a
chromatograph, but a Flash Configuration change is
required to allow the chromatograph to be interfaced to
COM3.
Power System, Charge Regulator
and AUX Output
You can choose from a variety of internal power systems
that includes lithium batteries and rechargeable lead acid
cell batteries, the latter of which are matched with solar
panels as charging sources.
All associated electronics are included on the
Processor/Main Electronics board, which is located on the
left-hand side of the enclosure.
Related to the power system, a charge regulator circuit and
an auxiliary output (AUX Output) are standard in
ControlWave GFC.
Bendable RTD
You can choose a bendable RTD that is attached to the
ControlWave GFC 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 is used to provide the process
temperature input, but the standard application program
also allows you 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-inch probe can quickly be inserted in a thermowell,
whereupon you 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 and B RTDs. ControlWave GFC
supports the full range in the DIN standard, -40 to 660ºC.
The DIN EN 60751 equation is:
RT = Ro * (1 + AT +BT2)
Where:
A = 3.9083 x 10-3 ºC-1
B = -5.775 x 10-7 ºC-2
Ro = 100 Ω
5
CWGFC
June 2012
In addition, you 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, you are able to set the
coefficients, restore the factory default for these
coefficients, and calibrate the internal reference resistor.
Thermowell Options for RTD
For new installations, or those lacking a thermowell, you can
choose one of three lengths of thermowell for the RTD.
I/O Configuration
Note that the base I/O (2 DI/PI) is located on the
Processor/Main Electronics board. Also, the RTD input and
MVT (Multivariable sensor) interface are located on the
Processor/Main Electronics board.
Additional I/O circuitry is located on an optional I/O card
that plugs in to the Processor/Main Electronics card. You can
choose between 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.
It is important to match the radio-ready configuration with
the specific radio you expect to install because cables and
connections for the antenna, RS 232 port, and power vary
by radio model.
Modem Specifications
The auto-dial/auto-answer modem is the same Cermetek
model that is used in the TeleFlow products. This modem
provides a sleep mode that conserves power while allowing
it to wake up when a call comes in.

What is the difference between a pulse input (PI) and highspeed counter input (HSC)? The HSC circuitry includes
debounce, which is useful with form ‘C’ relays, such as those
in some pulser devices. A PI does not include the debounce
circuitry and is, therefore, not recommended with relays.
Note that in the HSC inputs, the debounce can be
enabled/disabled by the user and they are shipped disabled.

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.

Polyphaser Option For Radio

If a radio is specified, you can select whether or not a
Polyphaser surge protector is included. Emerson always
recommends the Polyphaser.

Modem or Radio Option
For specifications on the radios, please refer to the Emerson
Process Management web site,
www.EmersonProcess.com/Remote, where individual data
sheets are available in pdf format.
Radios are standard models, which are widely available from
Freewave and MDS. Note that modems and radios are all
allocated to the network port, COM2, and are, thus,
mutually exclusive.
Since some users prefer to procure the radios separately,
Emerson offers radio-ready configurations for each of the
models. Radio-ready models include literally everything
except for the radio. The mounting bracket as well as all
cables and connections are in place. The user or
integrator/installer must simply mount the radio to the
bracket and make connections.
