Bildon Motorsport - Flow Bench Services Our flow bench has been calibrated with a sharp edge orifice plate to the American Society of Mechanical Engineers MFC-3M-1989 national standard. Our flow numbers are accurate, not inflated. Our bench is equipped with an advanced data acquisition and computerized control system. This system eliminates the hassle of traditional fluid manometers and has proven to be more accurate over a larger range than even the best manometers. Microprocessor control increases both the accuracy and repeatability of our flow testing. High quality pressure sensors accurately read control pressure (depression), flow (CFM), velocity, temperature and humidity. Operator to operator variations are minimized.
Another benefit of using a computer controlled bench is the ability to use our own software for analysis. Our software automatically measures test pressure and temperature and shows corrected flow on a graphical display. Our bench automatically regulates the test pressure with a 'stepper' motor pressure control valve operated by the flow bench computer. We select the test pressure at the beginning of the test, and the computer regulates the test pressure (usually 28") automatically as the valve lift is changed. This is far more accurate and faster than fiddling with a series of knobs and valves as was needed in the past. All analyzed data is simultaneously transmitted in real time to our computer where post test processing can be done in any of a number of software programs such as our own Excel macros and PT's Port Flow Analyzer.
Below is some of the output that we can provide our customers with when we complete a full flow analysis of their head. Up to 25 Valve check lift points in .050" steps or L/D stages Post Test Analysis:
