Welker IRA Automatic Insertion Probe Regulator

IRA

Automatic insertion and pressure regulation for real-time natural gas analyzer sampling

The Welker IRA Automatic Insertion Probe Regulator combines sample extraction and pressure regulation in one device for real-time natural gas analyzer sampling. Designed for high-volume natural gas pipelines with a full port isolation valve, the IRA delivers a continuous representative sample stream at the proper analyzer pressure while allowing insertion and retraction at full pipeline pressure. With adjustable insertion depth, regulation at the probe tip, low line pack, diaphragm control, and AI Control™ safety, the IRA helps reduce lag time, mitigate Joule-Thomson cooling, and protect sensitive analytical equipment.

Where to Use

Natural Gas Analyzer Sampling

Upstream of an analyzer as a standalone pressure control device or part of a sample conditioning system.

High-Volume Natural Gas Pipelines

Designed for natural gas pipelines with a full port isolation valve where insertion, retraction, and maintenance may be needed without interrupting operation.

Complies With:

API 14.1 GPA 2166 ISO 10715 AGA Manual

Automatic Insertion Probe Regulator

Combines sample extraction and pressure regulation in one device to simplify analyzer sampling systems.

Insertable and Retractable at Full Pipeline Pressure

Allows maintenance during continuous pipeline operation without costly shutdowns.

Adjustable Insertion Depth

Positions the probe for representative sampling from the pipeline stream while supporting use across multiple applications.

Regulation at the Probe Tip

Reduces line pack and helps deliver a properly conditioned sample stream to the analyzer.

Probe Design That Mitigates Joule-Thomson Cooling

Helps reduce the creation of free liquids and supports more accurate online gas analysis.

Diaphragm Design

Provides responsive low-pressure output sensitivity for analyzer protection and stable pressure control.

AI Control™

Supports safer insertion and retraction for greater operator confidence.
