Vortab Flow Conditioners
Many flow meter technologies, require several diameters of straight pipe run to meet their published accuracy specification. This straight-run is required to provide a swirl-free and repeatable flow profile to the flow meter.
However, in practical applications, industrial plant piping is rich with elbows, valves, tees and vessels. 20 – 30 diameters of straight pipe can be a real challenge to find. Pipe bends & valves create an unrepeatable, asymmetric and swirling flow profile ultimately resulting in flow meter inaccuracies.
Furthermore at low-flows the transitional zone between laminar and turbulent flow can induce additional inaccuracies.
The Vortab range of flow conditioners can eliminate these errors in as little as 3 pipe diameters.
Vortab Design Solutions
Vortab flow conditioners are available in straight-pipe runs, a unique 90° elbow, and insertion panel designs for virtually any pipe, tube or duct size.
VEL Elbow Flow Conditioner
The VORTAB Elbow 90° long radius elbow (model VEL) flow conditioner offers a simple flow conditioning elbow replacement for new and existing piping systems. The VORTAB Elbow flow conditioner is the only true isolating elbow flow conditioner in the world.
VIS Insertion Sleeve Flow Conditioner
The VORTAB Insertion Sleeve Flow Conditioner (model VIS) is the most cost effective version of the Vortab flow conditioning products. The VIS can be installed directly into existing pipe or specially designed round, square or rectangular ducts.
VIP Insertion Plate Flow Straightener
The VIP (VORTAB Insertion Panel) flow conditioner completely neutralizes flow profile irregularities caused by elbows, valves, blowers, compressors, and other flow disturbances that commonly occur in piping and duct runs and cause flow meter inaccuracies. The VIP provides a swirl-free, symmetric and repeatable flow profile that flow meters require for accurate measurement.
VMR Meter Run Flow Conditioner
The VORTAB Meter Run flow conditioner (model VMR) offers a complete, simple pipe section replacement for new and existing piping systems. The VMR is a seven pipe diameter long spool piece comprised of three pipe diameters of Vortab flow conditioning internals and a built in downstream settling chamber.

Know your Reynolds numbers !
Accurate flow measurement between Reynolds numbers 2,000 to 4,000 Re can be a major problem. The Vortab VIP flow conditioner is an ideal solution.
