Awesome project! Do you take it and measure pressure and flow rate at different places in a building a lot? This seems a very handy tool for that. Since you bought stuff from Seeed, you know they also have blue tooth bees, right? You could replace the display and buttons with blue tooth link to your phone Just run a Bluetooth terminal program and you can save all logs. Of course that will not be fool proof any more.
Very cool. I've thought of pairing a couple of flow sensors like this (for our science models, see www.emriver.com); but how do you handle more than one interrupt with Arduino?And seems those sensors would have a pretty good pressure drop; unless your flow rates are not that high; that's my problem with the impeller sensors.And you're a good plumber; if I put the electronics and wet parts in one enclosure they would not last long! :-)
Well done !
