I am new to Arduino but I believe this could offer me a perfect solution for this project.
Boeing is requesting a "smart" flow tester from us to test coolant flow in their tools, we already have a Omega A2317 MAF Reader which has an Output signal: Linear 0 to 5 Vdc, 1000 Ω min load, 4 to 20 mA, 500 Ω loop resistance.
We would like to monitor this output and, depending on tool diameter and length, illuminate a red or green light (pass/fail).
Unfortunately, Omega does not provide the linear graphs for voltage output corresponding to flow, so it would have to be taught.
This requires a keypad for input, a monitor (or a touch screen and eliminate the keypad) lights, and a searchable table of the correct flows for the range of our tools which they use.
Thanks for the help,
