IRA-4SS Probe Regulator

Brand: Welker, Inc
The Welker IRA-4SS Probe Regulator is designed to regulate a gas sample stream to an analyzer without interrupting pipeline flow.

With AI Control™, the probe automatically inserts and retracts using pipeline pressure.

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. Marrying two of our leading products, we designed the Welker Original IRA-4SS Automatic Insertion Probe Regulator to do just that. The safety, convenience, and responsive control you need for accurate online sampling is here in a single user-friendly device.
Features
  • Provides properly conditioned sample stream 
  • Insert and retract probe at full pipeline pressure  
  • Easily adjustable to multiple insertion depths  
  • Point of regulation occurs at the tip of the probe in the flowing stream 
  • Probe design inhibits creation of free liquids and mitigates the Joule-Thomson effect  
  • Diaphragm design for optimizing low-pressure output sensitivity
Benefits
  • Proven safety with AI Control™ provides peace of mind  
  • Reduces line pack for analyzer applications  
  • Probe retraction design allows maintenance to be performed during continuous pipeline operation  
  • Design allows for easy installation and intuitive operation  
  • Transferable from location to location
