A flow mixer and conditioner for use within a conduit conditions flowing media within the conduit to provide a swirl-free, symmetric, and reproducible velocity profile regardless of upstream flow distortions, disturbances, or anomalies. Tabs are cut from a single plate and bent or affixed to provide mixing and conditioning of the flowing media. Single tabs or tab pairs emanating from common vertices can be formed so that they diverge in, or against, the direction of flowing media. The flow conditioner requires as little as three pipe diameters downstream and upstream to mix and condition the flow stream allowing close placement to elbows, valves, tees, and other disturbances typically seen in industrial plants.
