Bristol® ControlWave® XFC

Gas Flow Computer

Bristol® ControlWave® XFC, from Emerson Pro­cess Management is a cost effective, competitive
solution when requirements call for a chart replace-

ment or ow computer in a compact, explosion-

proof package.

Additionally, ControlWave XFC provides extended

capabilities, such as a second meter run or plunger
lift control, while maintaining the convenience and
simplicity of an integrated, explosion-proof installa­tion.

ControlWave XFC Overview

Hardware/Packaging Features

Using the gauge pressure sensor, ControlWave
XFC provides accurate, P/T measurement for linear
meters, including positive displacement, turbine
and ultrasonic technologies. The multivariable,

DP/P sensor applies best to orice metering, where

accurate, three-variable (DP/P/T) measurement is
required.

Specications

Emerson’s Bristol Sensor Assembly

can change it out and continue operating with the

"top end" electronics, including ow 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 user’s 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
(please refer to the last page of this product data).

pressure sensor or "142" for a 300" DP/2000 psig
static pressure multivariable sensor assembly.

Using the integral sensor assembly is the easiest

implementation for a single meter run; however, the

standard application program also allows use of

external transmitters.

Multiple-run systems can use the integral sensor

assembly for the rst run and an external, smart

multivariable transmitter, such as the Bristol 3808

MVT from Emerson(which includes the exact same

sensor assembly), for additional meter runs.

Communication Port Conguration for the

Standard Application Program

COM1 – Local RS 232 port for conguration via a
PC. Flash conguration is BSAP Slave, 115.2K

baud rate.

COM2 – RS 232 Network port with Flash congu­ration of BSAP Slave, 9600 baud. The standard

application program is compatible with an external

communication device via RS 232.

COM3 – RS 485 port with Flash conguration of

BSAP Master at 9600 baud. The standard appli­cation program assumes that a 3808 MVT smart
multivariable transmitter is to be interfaced to this
port.
