PTS Flowbench

The PTS Flowbench was a DIY project to build a flow bench capable of matching the performance of expensive commercially available flowbenches and to allow me to flow items I was interested in as well as to verify vendor claims.

The following photographs show the progress of the project and the completed PTS flowbench.
