The VIP Flow Conditioner is designed to eliminate flow profile distortions caused by upstream disturbances such as elbows, valves, blowers and compressors.
Using Vortab’s patented tab-type conditioning technology, the VIP produces a swirl-free, symmetric and repeatable flow profile, allowing flow meters to operate at their specified accuracy even in challenging installations.
Unlike traditional conditioning methods, the VIP can achieve this performance with minimal straight pipe requirements and very low pressure drop, making it ideal for retrofit applications where space is limited.
Key Features & Benefits

Provides repeatable, stable flow conditions for accurate measurement
Requires as little as 3 pipe diameters of straight run
Very low pressure drop compared to traditional flow straighteners
Ideal for retrofit installations and constrained pipework
Suitable for gas applications and wide turndown flow systems
Typical Applications
- Thermal mass flow measurement systems
