Welker Constant Pressure Cylinders were
originally designed for the transportation
of light liquid hydrocarbon samples in the
early 1970's However, with the introduction
of British Thermal Unit (BTU) measurement,
the constant pressure cylinder has become
an important aspect of natural gas sampling
As prices rise or drop for oil and gas,
accuracy of a sample is most important Having
to account for everything which moves through
the pipeline, the sample carried to the
laboratory is dollars lost or gained.
Not only does the constant pressure cylinder
allow you to transport at pipeline pressure,
but equally important, it can be equipped
with mixing capabilities All2-inch diameter
constant pressure cylinders are DOTand DNV
type approved Other Welker cylinders are
available in dozens of designs and sizes.
