IRD Series Natural Gas Analyzer
Brand: Welker, IncFor real-time natural gas analysis of high-volume lines, you need a sample probe that can deliver a continuous supply of representative samples to your analyzer at the appropriate pressure.
The Welker Original IRD Probe Regulator mounts directly to a hot tap or mating flange on your depressurized pipeline and has a fixed insertion length to extract the most representative sample from the center one-third of the source stream.
Features- Fixed insertion length
- Pressure-regulating probe tip with thermal fins
- Low internal volume
- Multiple pressure control ranges
- Welker Spring Range Kit (IRD-4SS option)
Benefits
- Collect representative samples from the center one-third of the pipeline
- Regulation point in the pipeline
- Mitigate the Joule-Thomson effect and prevent sample condensation
- Reduced lag time
- Real-time sample analysis
- Adaptable to pressure requirements of downstream analyzer
- Easily swap springs to change the output pressure range for a new application or downstream device (IRD-4SS option)
