VSR - VORTAB Short Run Flow Conditioner

The VORTAB Short Run flow conditioner (model VSR) offers a simple flow conditioning pipe section replacement for new and existing piping systems. The VSR is a three pipe diameter long flow conditioning spool piece with just the VORTAB flow conditioning internals.

Three to four diameters of settling distance between the VSR and the flow meter installation location are required to allow the turbulence intensity to decrease while maintaining the repeatable velocity profile. This provides an optimal flow scenario for flow meters of all technologies installing the VSR flow conditioner can be accommodated by a variety of process connections including flanged, threaded, grooved, weld prepped, or customer specified. VORTAB flow conditioners provide the lowest pressure loss solutions to flow profile irregularities caused by elbows, valves, blowers, compressors and other disruptions that commonly occur in piping and duct runs.
