Advanced Flow Straightening Solutions

Uniform flow modules for flume channels and circular conduits.

Modular flow straighteners help labs reduce turbulence, improve velocity profile uniformity, and maintain repeatable upstream conditions across open-channel and closed-conduit research systems.

Configurations

Panel-based designs that scale with the flow conditioning requirement.

Single-panel flow straightener mounted in a flume channel

01

Single panel per stage

A robust full-width panel configuration for multi-stage open-channel installations where simple removal and scalable straightening are priorities.

  • No vertical joints in the flow path
  • Simple, robust construction
  • Easy single-panel removal
Typical stages
2 to 4 in series
Material
Aluminum or stainless steel
Cell size
Square cells, typically 50 mm x 50 mm
Two-panel stacked flow straightener mounted in a flume channel

02

Two panels per stage

Horizontally stacked panels balance conditioning performance with practical handling for maintenance, cleaning, and stage-by-stage installation.

  • Top and bottom panels per stage
  • No vertical joints in the flow path
  • Good balance of performance and handling
Typical stages
2 to 4 in series
Panels per stage
2
Stage depth
About 100 mm, customizable
Eight-panel flow straightener mounted in a flume channel

03

Eight panels per stage

Two stacks of four panels provide high straightening performance for sensitive measurement environments and demanding velocity-profile requirements.

  • Highest straightening performance
  • Eight removable panels per stage
  • No vertical joints in the flow path
Typical stages
2 to 4 in series
Panel layout
Two stacks of four
Best for
Sensitive measurements
Circular flow straightener mounted in a pipe channel

04

Circular straighteners

Circular modules apply the same removable-panel concept to pipes and circular channels, with one or more stages selected around the target flow condition.

  • Uniform flow straightening in circular channels
  • One or two stages available
  • Removable panels for maintenance
Typical stages
1 to 2
Material
Aluminum or stainless steel
Application
Pipes and circular conduits

Design Features

Built for research systems that need stable flow and practical maintenance.

Uniform flow

Reduces turbulence and improves velocity profile uniformity.

Full-width flow area

No vertical center supports, preserving full flow capacity.

Durable materials

Aluminum or stainless steel for corrosion resistance and service life.

Easy maintenance

Lightweight removable panels lift out for cleaning and inspection.

No center obstruction

Full-width designs eliminate vertical joints and reduce pressure loss.

Modular and scalable

Use one or more stages in series to meet conditioning needs.

Smooth and cleanable

Smooth surfaces and open-cell structure are easy to rinse clean.

Customizable

Cell size, panel thickness, stage depth, and stage count can be tailored.

Comparison Summary

Select the design around performance, handling, and channel geometry.

Design Total panels per stage Stages in series Relative performance Pressure loss Best use cases
Single panel 1 2-4 Moderate to high Moderate General-purpose, flexible, and scalable applications
Two panels 2 2-4 High Moderate Most common applications with a good balance of performance and handling
Eight panels 8 2-4 Very high Higher High-performance requirements and sensitive measurements
Circular 2 per stage or 4 total 1-2 High Moderate Pipes and circular channels
