IRD Probe Regulator

Brand: Welker, Inc
Request Information
The Welker Original IRD Probe Regulator delivers a continuous supply of representative samples to an analyzer at the appropriate pressure for real-time natural gas analysis of high-volume lines.

For 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)
