To use the most common differential pressure meters the flow in the line needs to be as smooth as possible, i.e. without turbulence. Flow Straighteners are designed to remove swirl and to restore an acceptable reference profile geometry in a line where installing of sufficient straight length is not possible.

Depending on the amount of swirl and distortion and the allowable permanent pressure loss, several types of Flow Straighteners are available, such as ‘Zanker’, ‘Etoile’, ‘Sprenkle’, Tube-bundle, AMCA or AGA/ASME types.

Den Holder manufactures Flow Straighteners in any required material and dimension for any required pipe standard.
