ABB MEASUREMENT & ANALYTICS NGC8209 Natural gas chromatograph

software designed specifically for the NGC8209. provides a

powerful tool for operations, diagnostics, and downstream

data handling. The PC can be directly connected to the

NGC8209 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

pushbuttons, dropdown boxes, wizards, and dialog boxes for

setup, operations, data collection and monitoring.

In addition, the unit has a ¼ VGA interactive display screen

allowing the user to access basic analysis data and perform

basic operations.

Maintenance

The NGC8209 was designed to be maintained by personnel

with little or no prior knowledge of Gas Chromatography.

Both hardware and software are designed to provide low

maintenance through easily replaceable electromechanical

modules such as:

• NGC termination panel

• NGC analytical module, an easily removable chromatograph

subassembly, containing:– NGC manifold– Stream selector solenoid valves– GC module– Dual electronic carrier–

 Pressure regulator valves– Chromatograph pilot valve– NGC analytical processor

• NGC feed-through (heater optional)

• Sample conditioning module (SCM)

• NGC controller (32 bit Processor)

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

• Remote or local operation of PCCU

• Quick Start Guide and User Manual

Historical data

The NGC8209 is designed to retain historical data. This data

can be used for custody transfer needs, to verify transmitter

operation over time, and to provide a limited data backup for

communication link reliability. The user is allowed to

configure the period of the data retained by the NGC8209 via

the Operator Interface.

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

• HCDP

• Alarms

The default¹ stream averages is 840 hours, 35 days, and 14

months of data analyses. This data can be used to evaluate

performance:

• Selected peak times

• Selected peak areas

• Ideal Btu/CV

• Individual component mol %

(Diagnostics report):

• 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 NGC8209 can be collected via a remote

communication link or by the laptop PC local operator

interface PCCU.

1  The default memory configuration will provide for the data storage

above. The user may reallocate the memory that is available.
