#8 FC Flow Conditioners

Stabilize Flow Profile
Tube Bundle, Plate Types

  • Ensure optimal accuracy
  • Reduce required upstream length
  • Various styles and designs are available


Flow conditioners are supplied in two general styles, Straightening and Isolating. Straightening flow conditioners, such as a tube bundle, are effective at removing swirl from a flowing fluid, but less effective at normalizing longitudinal velocity variations from the fluid. Isolating conditioners, such as a plate type, are effective at both removing swirl and redistributing the flow profile symmetrically. Additionally, plate type conditioners typically produce less pressure loss than tube bundle types.

Please note: The term flow conditioner is used both to describe these products generally and may also be used when referring to a plate type unit.


Function Purpose
Flow measurement accuracy is maximized when a flowing fluid’s velocity profile is uniform. When the velocity profile is disturbed or altered by disturbances such as bends, diameter change or protrusions into the flow, flow conditioners can be installed to restore the flow to a uniform profile. They can also be used to reduce the amount of straight pipe required upstream of a differential producing device while maintaining optimum accuracy.
Service Functional Limits
Flow Conditioners will accommodate the rating of the pipe system in which it is utilized.
