First time poster here so let me know if I'm missing key info.
I'm helping a friend create an Arduino-powered data collection system for his coffee roaster, and we'd like to track the natural gas pressure (in W.C.) being sent to the burners.
Can anyone recommend a low-cost solution for this? I think we'd have to have a plumber install it, because it should be inserted into the pipe leading to the already-installed analog readout and allow us to push data to a microcontroller. I don't know the exact diameter of the copper pipe but I think it's a standard size. Even if someone could point me in the direction of the right class of device and/or a manufacturer, that would be great.
EDIT: The range we need is 0-16" W.C. or 0-40 mbar
