Why Straight Pipe Needed Before and After Flow Sensors?

by | Nov 25, 2025 | 0 comments

Straight pipe sections before and after a flow sensor are essential to stabilize the flow profile. This reduces turbulence and ensures accurate, repeatable measurement results.

In this particluar case a flow meter is used to determine the flow and the total consumption of compressed air. The flow Almost all modern flow sensors require a so-called fully developed flow profile for accurate measurement. This profile is disturbed by obstacles and the direction changes in the pipeline and must be “straightened” over longer straight runs. That`s why particular inlet and outlet sections are defined and specified in multiples of the pipe diameter.
