By measuring the volume of air that can be passed through the item the user can determine if modifications help improve air flow characteristics./p>p>Traditionally constructed of a manometer and calibrated flow orifices, volumetric flow was calculated using mathematical methods. Modern flow benches use sensors to detect flow and reference pressures, flow calculations are now undertaken by microprocessor./p>h2> /h2>h2>a iduser-content-what-is-the-diy-flow-bench-project classanchor hrefhttps://github.com/DeeEmm/DIY-Flow-Bench#what-is-the-diy-flow-bench-project>/a>strong>What is the DIY Flow Bench Project?/strong>/h2>p> /p>p>strong>img styledisplay: block; margin-left: auto; margin-right: auto; src/images/screenshots/AltTiles.png width1000 height732 loadinglazy data-pathlocal-images:/screenshots/AltTiles.png />/strong>/p>p>The DIY Flow Bench project (DIYFB) is a professional quality flow bench controller that produces results comparable with, and in some aspects exceeding commercial grade systems./p>p>The project comprises of two basic aspects./p>p> /p>h4>strong>Software/strong>/h4>p>The software code is developed in C++ and runs on an ESP32 microprocessor. The ESP processes sensor data and uses the results to calculate volumetric flow data, which is then displayed via web browser on any web enabled device. The system can be used as a floating or fixed reference depression bench. When used as a floating reference bench the depression is automatically converted to a fixed value on-the-fly, allowing flow readings to be viewed at any chosen depression value./p>p>The software also includes provision for data recording, allowing tests to be saved for later viewing and analysis./p>p>The code is open source and is available under the GNU GPL V3 license./p>p> /p>h4>strong>Hardware/strong>/h4>p>The hardware aspect of the project comprises of a PCB (commonly known as a shield) which connects to the ESP processor. The PCB includes environmental sensors to measure temperature, humidity and barometric pressure along with pressure sensors to measure the reference depression from the vacuum source. The shield also interfaces to a MAF sensor which allows the software to accurately measure and calculate volumetric flow. The circuit schematics are also open source which allows people to develop their own shields should they wish./p>p>Both the software and hardware aspects of the project are available for free from the projects GitHub repository. The GitHub repo also contains all of the information needed to build your own volumetric flow bench in the form of a WIKI and Support forum./p>p>The system supports the following systems architectures./p>ul>li>MAF based benches/li>li>Orifice based benches (In Development for V3 release)/li>li>Pitot style benches (In Development for V3 release)/li>li>Venturi style benches (In Development for V3 release)/li>/ul>p>The DIYFB system can therotically be used on any flow bench and makes an ideal retrofit for older manometer based benches as well as being the perfect choice for new builds. We include DIY hardware plans so you can build a basic MAF based flow bench that uses a shop vac for the vacuum source. This is a great entry level bench and perfect for most shops and hobbyists. We also provide support for larger and more complex bench designs./p>h2> /h2>h2>a iduser-content-project-goals classanchor hrefhttps://github.com/DeeEmm/DIY-Flow-Bench#project-goals>/a>strong>Project Goals/strong> /h2>ul>li>Validated software and hardware design./li>li>Affordable & easy to source components./li>li>Can be built & operated by a layman./li>li>Generates results comparable with commercial flow bench./li>li>Open source software and hardware design./li>li>DIY Shield kits available to purchase./li>/ul>h2> /h2>h2>strong>Specifications/strong> /h2>h3> /h3>h4>Hardware/h4>ul>li>Reference pressure (depression) sensor./li>li>Differential pressure sensor (for orifice / venturi / pitot based benches)/li>li>Pitot sensor (Differential pressure sensor for pitot probe)/li>li>MAF sensor (voltage and frequency* based sensors are supported)/li>li>Temperature/li>li>Barometric pressure/li>li>Humidity/li>li>Swirl Probe support*/li>li>Serial Gauge protocol* (for recording valve lift data)/li>li>DAC VFD control for vacuum motors/li>li>DAC Bleed valve control/li>li>Multi stage vac motor control/li>li>Stepper motor control for bypass valve*/li>li>Stepper motor control for automatic valve lift control*/li>li>High speed input for turbine speed monitoring*/li>li>Automatic orifice detection (for orifice / venturi / pitot based benches)*/li>li>SD Card support for Data storage./li>li>Wifi /li>li>Serial API interface/li>/ul>p> /p>h4>Software/h4>ul>li>Wifi connectivity management/li>li>Browser based GUI/li>li>Serial based API/li>li>Realtime display for flow / depression / temperature / barometric pressure / humidity / differential pressure / pitot / swirl/li>li>User configurable system settings via GUI/li>li>GUI based calibration/li>li>Auto leak test function/li>li>GUI based data handling/li>li>Automated vacuum motor control/li>li>Lift vs Flow graphs*/li>li>Support for digital gauges*/li>li>Support for automatic valve operation*/li>/ul>p> /p>p>*support scheduled for V3 release/p>p> /p>h2>a iduser-content-download classanchor hrefhttps://github.com/DeeEmm/DIY-Flow-Bench#download>/a>strong>Download/strong>/h2>p>You can download the latest release from our a hrefhttps://github.com/DeeEmm/DIY-Flow-Bench/releases>Githib repository/a>/p>h2> /h2>h2>a iduser-content-support classanchor hrefhttps://github.com/DeeEmm/DIY-Flow-Bench#support>/a>strong>Support/strong>/h2>p>Documentation is provided for installation, configuration and use in the a hrefhttps://github.com/DeeEmm/DIY-Flow-Bench/wiki>WIKI/a>/p>p>If you get stuck, feel free to create a a hrefhttps://github.com/DeeEmm/DIY-Flow-Bench/discussions/>discussion/a> in the support forum, or hit us up over on the a hrefhttps://discord.gg/eAbktJj relnofollow>Discord/a> channel./p>p>If you find an issue, or have a feature request, please a hrefhttps://github.com/DeeEmm/DIY-Flow-Bench/issues>raise an issue/a>/p>p> /p>h2>a iduser-content-license classanchor hrefhttps://github.com/DeeEmm/DIY-Flow-Bench#license>/a>strong>Licenses/strong>/h2>h4> /h4>h4>Software/h4>p>The software aspect of this project is released under the GPLV3 license.
