VEL VORTAB Elbow™ Flow Conditioner


VEL Flow ConditionerThe 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. It not only has the ability to isolate irregular velocity profiles and swirl normally encountered in a single elbow, but it also has the ability to isolate any irregular velocity profiles entering the Vortab Elbow.

A repeatable, symmetric and swirl-free velocity profile is an optimal flow regime for flow meters. Even pumps and compressors require three to ten pipe diameters of un-obstructed straight run upstream from their inlets. An uneven distribution of the flow stream into impellors can result in severe suction recirculation, excessive bearing wear, erosion, noise, and increased maintenance costs. The Vortab Elbow flow conditioner reduces these velocity profile anomalies and can be fitted with a multitude of process connections to ease installation, as you can preview in these drawings 004579, 004581, 004580. Vortab Elbow can also be supplied with extended settling chambers and flow element connections to accommodate flow meters and other critical process equipment as you can preview in these drawings 004582, 004583, 004584, 004585, 004586, 004587, 004599, 004589, 004590. The settling chamber allows the turbulence intensity to decrease while maintaining the repeatable velocity profile. This creates an optimal flow scenario for flow meters of all technologies. 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.
