Integrated stream switching

The integral stream selector for the NGC8207 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”.

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.).

• NGC ¼ VGA display (optional)

Other maintenance support features

• Intuitive Local Operator Interface (PCCU 32) running

Microsoft® Windows® environment

• Diagnostic software and wizards for maintenance

• Diagnostic file output system for e-mail support

• Digitized detector output (chromatogram) to PCCU 32

• Remote or local operation of PCCU 32

• Quick Start guide, Start up manual and Start up video

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

• Detector noise values

• Detector balance values

Audit logs (default¹)

• Last 480 alarms

• Last 480 events

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.

The default¹ memory configuration provides the most recent

480 analysis cycles containing:

• Normalized components

• Un-normalized components

• Ideal Btu/CV

• Real Btu (wet and dry) / CV (superior and inferior)

• Relative density (specific gravity)

• Density

• GPM

• Wobbe index

• Alarms
