A flow bench is a tool. Properly set up and calibrated at the same depression of water it should read the same or within a small percentage to
any other flowbench. Not properly calibrated or otherwise fooled with it will give different numbers, for whatever reason... but that is the operator's
fault and not the flowbench's.
You can fool with your torque wrench to give a different reading, but would you do that just to please yourself? Guess not, LOL.
