Diffusing Probe

Diffusing Probe

Uniform Odorization

Designed for use with injection odorizers, Welker’s diffusing probe allows for rapid odorant dispersal across the full diameter of the pipeline, ensuring uniform odorization, even during times of variable flow.

Enhanced Odorant Vaporization

No Drips, No Puddles

Inside the porous probe is a braided nylon wick, which absorbs the liquid odorant. As natural gas flows through the perforations in the probe, the liquid odorant is vaporized more easily and distributed more evenly in the gas stream compared to a traditional drip probe.

Even Distribution
Welker’s diffusing probe is available in the insertion style that meet your pipeline needs.
