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.

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

Fixed

Choose fixed to install the probe to a depressurized pipeline.

Adjustable

Choose adjustable to insert the probe at lower pipeline pressures.

Automatic

Choose automatic to insert the probe at full pipeline pressure.
