Application Note

Gas Quality Simplified
The analyzer system includes all required sample conditioning and regulation. The sample system is heated to 50°C (122°F) to keep all constituents in vapor phase.

Training requirements are reduced and the system enables fewer electrical runs, fewer sample runs and less labor. Installation and operational costs are dramatically reduced.

The Installation diagram on the left is a simple representation of connection to the pipeline.

A variety of sample probe products are available to compliment the application.

SpectraSensors offers probes, probe regulators, and heated regulators depending on the pressure in the pipeline, the gas and ambient temperatures and the hydrocarbon dew point.
