Major oil companies
and petroleum cargo inspection agencies worldwide
rely on the Welker Crude Oil Sampler for pinpoint
accuracy and reliability. The Welker Crude Oil
Sampler extracts a representative sample from
a properly conditioned line and pumps it into
a sample container. Using an isokinetic collectionhead,
the sampler allows you to analyze the sample to
determine BS&W, API gravity, shrinkage and
the chemical composition.
A wide variety of sample volumes (.065 cc to30
cc) and insertion methods (fixed or removable)
are available.
