The patented Welker Light Liquid Hydro-carbon Sampler determines
the quality of the flowing stream with highest accuracy. It
collects and stores product samples over a given period of time
without changing the phase of the sample. With its Vanishing
Chamber® collection head, which totally voids itself prior
to sampling, the sampler allows the product to flow through
its body. It is capable of pumping from lowest to highest pressures
with no venting to atmosphere. In addition, a patented, pressure-balanced
vortex mixer operates either manually or automatically to ensure
a proper mixture regardless of how light or heavy the product.
The sampler's simple design, high reliability and minimum maintenance
requirements ensure 100% integrity of sample handling
