This is a valid option but we instead opted to build a motor controller.
Diy flow bench.
With high tech electronic sensors and a patented state of the art air flow metering element effective flow rate measurements can now be made with nothing more than an average shop vac for an air source.
Currently the project is focused on making a basic flow bench using an automotive maf sensor and arduino controller.
It is and has been for decades an invaluable tool to any one interested in increasing the performance of combustion engines.
Generally most diy flow benches modify flow rate by using a manual valving system.
The diy flow bench projects aim is to build a basic affordable diy flow bench using readily available components.
Open the 5 cfm orifice.
Establishing the numbers step 1.
A flowbench or air flow bench is a tool to measure the air flow capabilities of anything that s required to do this.
The diy flow bench is a basic system to measure and display volumetric air flow.
This flow bench uses a shop vacuum for estimated flow data.
Diy flowbench design diy flowbench design and construction what s a flowbench.
While using a shop vacuum to move air through the flow bench the fp1 processor estimates the flow data to 28 wc test pressure in real time as the flow test is being performed.
Benches are appropriate both indoors and outdoors and can be used for storage for decoration or just to sit on and reflect.
One of our favorites is a diy bench which is always a great way to provide a practical and decorative accent both inside and out.
Start with a reading on the manometer with the plate completely blocked off for a zero flow depression test.
This micro flow bench is the most basic easiest to build flow bench using the flow performance kit fp2 0bs.
