Remote Automation Solutions

ControlWave

GFC Gas Flow Computer

Featuring the “Express” Electronics

Platform

When requirements call for an integrated “all in one box”

chart replacement or flow computer, ControlWave

GFC,

from Emerson Process Management, is a cost effective,

competitive solution.

Unlike chart replacements, ControlWave GFC is also able to

meet your automation needs and easily supervises a two-

run metering and regulating station or plunger lift

operations at a well site.

Hardware/Packaging Features



32-bit ARM9 platform is capable of multiple flow

computing and process automation operations.



Gauge pressure or DP/P sensor assembly can be

removed and replaced independently of the “top end”

electronics.



Precision RTD interface provides very accurate

measurement.



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 AO.



Integral LCD with optional 25-key keypad allows you to

view and change configurable parameters on site,

without packing a PC.

 Broad selection of modem and wireless

communications options are available.

Firmware/Software Features



ControlWave GFC is pre-programmed to meet API 21.1

requirements for a two-run metering station with

networking via BSAP or Modbus.



Web-style menu pages are pre-configured for all user

operations.



Using our ControlWave Designer, IEC 61131-3

programming environment, any user or third party can

modify the standard application or create a completely

customized program and the full support from

Emerson is available every step of the way.

 Additional standard application programs will be

introduced on a continual basis.

ControlWave GFC

Application Areas

ControlWave GFC 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

ControlWave GFC Package

Overview

ControlWave GFC is delivered in a compact Lexan enclosure

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.

CWGFC June 2012 MVT Assembly Static Pressure Orientation 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.

CWGFC June 2012 The Hourly Data Log holds one record for every contract hour. Hourly logs hold 840 entries or 35 days; this ensures that the previous period of hourly data is always resident in ControlWave GFC FLASH memory. The following items are stored in the Hourly Data Log: Overview of the Standard Application Program: Uses pre-configured web-style menu pages for user readings, configuration, and maintenance.

CWGFC  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.

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.
