Flowbench Plans 

• The PTS plans were designed using proven design & ideas/tips discussed and tested by members of my Flowbench Forum on their own homebuilt flowbenches. 
• The PTS plans are based on an orifice style bench using my orifice plates (or your own design) it offers reverse flow for intake or exhaust testing by flipping the orifice plate and reversing the slider plate. 
• This bench is not based on a shop vac or knock-off of the MSD design! 
• The "foot-print" of the bench is 36"w x 25"d x 40"h.
• Think of the plans as a "condensed version" of all the information found free on my Flowbench Forum you save time having to find it all by purchasing a set.
• The plans are not a photocopy of magazine articles!! They are an original design based on proven design.
• Ranges can be changed with different size orifice plates. 
• There is no rotating orifice disk which can be prone to leakage.
• No additional Flow Elements are required for this bench design, all flow measurement is performed with the orifice plate inside the bench.
  
• The slider plate is the only moving part in the bench, no valves or disks.
• Gages are digital based, you will need to purchase digital gauges of your choice, (*see note below about the PTS Digital Manometer) or you can design your own water manometers from the info found on the forum, at the current time I'm not supplying this info in the plans but, it is currently under development in my shop and is available on the Flowbench Forum.
• Flow depression is controlled via electric motor control.
  (manual valve optional, not in the plans, supported on the Flowbench Forum)
• Has the capability of using 2-8 blower motors depending on your flow needs, 
  budget and power.
• The plans are fully supported on the Flowbench Forum for anyone who purchases the plans.
• This bench can be built on a budget (roughly around $500) or buying all new parts with a typical cost of less than $1000.
• This bench design is very accurate and repeatable, all of which depends on your attention to details in construction. I have many satisfied customers all over the world currently building or using my bench design!
• It is comparable in design to commercially produced flowbenches selling for $$$$ with the reputation and support of the Flowbench Forum to back it up . . .

PTS Digital Manometer (the wait is over!)   

* PTS Digital Manometer project allows you to go totally digital with PTS parts. No need to purchase a commercial flow computer, our PTS DM allows you to see and capture your data in real-time using a spreadsheet or database application. It features 3 pressure sensors (standard not an upgrade) and is fully supported on the Flowbench Forum. It comes as a pre-built unit ready to hookup to your PTS Flowbench you will need to supply a Windows 98/XP based PC or Laptop with a serial port.

More info can be found on the Flowbench Forum in the Flowbench DAQ area or checkout a sample video here. (Please keep in mind this is a preliminary video of the working prototype) 

Here is another small video of the bench flowing 400cfm@28" using 6 blowers.
