The vortex generating profile conditioning tabs
have the ability to cross mix the entire flow stream, regardless
of upstream flow disturbances or velocity profile distortion. Due
to the vigorous cross mixing of the flow stream, the velocity
profile exiting the VORTAB® is “flat” over
the majority of the flow stream and tapered off near the conduits
walls.
Flow conditioning upstream from flow meters to
ensure accuracy and
repeatability while greatly reducing installation requirements were
obvious new applications for this technology.
To eliminate flow meter anomalies induced by swirl in the flow stream,
anti-swirl vanes were incorporated into the design.
The final VORTAB design is a three pipe diameter long flow conditioner
which consists of eight anti-swirl vanes located at the immediate inlet
and three rows of four symmetrically aligned profile conditioning
tabs. The tapered design eliminates clogging and buildup on the
backside of the profile conditioning tabs. Debris buildup is non-existent due to the
pressure differential between the upstream and downstream sides of the
profile conditioning tabs. The final Vortab Elbow
90° elbow design
incorporates the same proven tab type technology to remove swirl
and velocity profile distortion. The rugged design and wide range
of product offerings support the installation of VORTABs and
Vortab Elbows in many installations. |
