Description

The NGC8206 analyzes each sample utilizing established

chromatographic techniques. The resulting information

consists of mole percent values for the following:

• “Air” (Contains N2, Ar, CO and O2 but not CO2)

• C1 CO2 C2 C3 IC4 NC4

• NeoC5 IC5 NC5 C6+

Using process chromatographic techniques, the columns are

back flushed so that the NGC8206 measures a C6+ peak. Users

may input the results of a comprehensive lab analysis that

reflects the split or ratio of C6 through C10 components. This

ratio can be used in subsequent analysis and energy

calculations. Calculated values include:

• Gas compressibility per AGA 8

• Real Relative Density (Specific Gravity)

• Btu/CV Value

• GPM (gallons of liquid per thousand cubic feet)

• Wobbe Index

• Methane Number

• Optional calculations can include: AGA 10 speed of sound,

Hydrocarbon Dew Point

Installation

The NGC8206 is a weatherproof device designed for

installation “on the pipe” near to the sampling point. This

means it is acceptable to mount outside – in a temperature

range of 0°F to 130°F (–18°C to 55°C) [provides reliable

operation for –20°F to 130°F (–29°C to 55°C) with low

temperature option] onto a pipeline with 2″ to 12″ pipe sizes or

with an optional pole mount configuration. A cold weather

enclosure is also available if ambient conditions are below

either the sampled gas dew point or the operational

specifications of the unit.
