Operator interface

Functional setup and operation of the NGC8207 is

accomplished by using a graphical user’s interface software

package named PCCU 32 (supplied with each unit) operating

on a laptop PC in a Microsoft® Windows® environment. The

“Windows®” utilities, combined with software designed

specifically for the NGC8207, provide a powerful tool for

operations, diagnostics, and downstream data handling. The

PC can be directly connected to the NGC8207 via an RS-232,

USB, or Ethernet connection, or indirectly by remote telemetry

(phone modem, radio, cell phone, satellite, etc.).

Operator interface

Functional setup and operation of the NGC8206

is accomplished by using a graphical user’s interface software

package called PCCU 32 (supplied with each unit) operating on

a laptop PC in a Microsoft® Windows® environment. The

“Windows®” utilities, combined with software designed

specifically for the NGC8206, provide a powerful tool for

operations, diagnostics, and downstream data handling.

The PC can be directly connected to the NGC8206 via an

RS-232, USB, or Ethernet connection, or indirectly by remote

telemetry (phone modem, radio, cell phone, satellite, etc.).

The user is prompted through push-buttons, drop-down

boxes, wizards, and dialog boxes for setup, operations, data

collection and monitoring.

In addition, the unit has an optional ¼ VGA interactive display

screen allowing the user access to basic analysis data. The

user can also accomplish most of the “operator” functions

from the front panel display with out the use of a laptop PC.

The “Run-Hold-Calibrate” functions can be done via a magnet

interface through the explosion proof glass in the display.

Sample conditioning system

The integral stream selector for the NGC8206 allows sampling

up to four (4) different natural gas streams. Up to two of these

sample streams can be designated as the “calibration/

validation sample”. Optional sample conditioning modules are

available to address natural gas streams that need additional

filtering and “speed loops” to reduce sample transport lag times.

In addition, the unit has an optional ¼ VGA interactive display

screen allowing the user access to basic analysis data. The

user can also accomplish most of the “operator” functions

from the front panel display with out the use of a laptop PC.

The “Run-Hold-Calibrate” functions can be done via a magnet

interface through the explosion proof glass in the display.

Stream averages for the (default¹) 840 last hours, 35 last days

and the most recent last month analyses. Operational

Parameters for the (default¹) last 480 cycles (Diagnostics Report):

• Selected peak times

• Selected peak areas

• Ideal Btu/CV

• Carrier regulator pressure

• Oven temperature

• Ambient temperature

• Sample pressure

Data retained by the Portable NGC can be collected via a

remote communication link or by the laptop PC local operator

interface PCCU 32.

Historical data

The Portable NGC is designed to retain historical data. This

data can be used for custody transfer needs, verify

transmitter operation over time, and provide a limited data

backup for communication link reliability.

In addition, various CSV file outputs are available to download

the analysis data into spreadsheet based company specific

data sheets, and outputs to 3rd party gas accounting

packages.

Equipment

The equipment used for this analysis consists of the standard

NGC8206 mounted in a powder-coated box. The equipment

used for this analysis consists of the standard NGC8209

mounted in a black case. It is recommended that the unit be

left in an operational mode while transporting.

All the valves, gauges, inlet ports, and PCCU32 (the laptop

driven man-machine interface) connectors are bulkhead

mounted on panel to provide the technician with ready access.

Description

The truck is moved as close to the sample point as is

practical. A flexible sample line is then uncoiled and attached

to the probe in the flowing natural gas pipeline. If the dew

point of the gas or the weather demands it, this flexible

tubing must be heated. A sample of the gas is extracted from

the probe in the line, purged through the flexible line and then

transported to the analyzer. There it is processed for particle

removal and phase integrity, injected onto the

chromatographic columns where component separation

occurs. These components are then quantified by peak

integration and concentration is calculated. The other data of

interest is then calculated from these concentrations.
