VORTAB Flow Conditioners Improve Flow Meter Accuracy

Process and plant engineers who need to add a liquid flow meter in
already crowded equipment areas where there is an insufficient straight
pipe run will find
VORTAB® Flow Conditioners ensure a
smooth flow profile for accurate measurement by flow meters, which often
must be installed in close proximity to pumps, valves or elbows due to
limited plant real estate. A number of popular liquid flow meter meters,
including differential pressure (dP), magnetic, ultrasonic and
turbines, feature sensing technologies that can be significantly
affected by asymmetrical flow conditions in the pipe. These conditions
degrade measurement accuracy and repeatability. Depending on the
particular technology, these meter sensing technologies require a
minimum of 6 to 10 upstream and up to 5 downstream straight pipe
diameters to a achieve a symmetrical swirl-free flow profile for
accurate measurement. Unfortunately, most process industry plants are
rich with bulky equipment and other real estate limitations, which make
it difficult to achieve the required pipe straight-run configuration
necessary for accurate liquid flow measurement. Many times too, plant
upgrades and retrofits require adding more flow meters in locations that
are difficult to accommodate without flow conditioning devices because
of their straight pipe run requirements. VORTAB Flow Conditioners reduce
the required straight pipe diameters to only a very few diameters for
effective compact meter installation and accurate flow measurement.
