Easy R.O solution - for people that constantly forget about the water

Most likely won't work for the low flow that RO units have. Most likely uses a "paddle Wheel" style magnetic pickup and they need a specific flow before they start to turn. Most accurate flow sensors are Doppler effect flow sensors, but they are pretty pricey. I use all kinds of flow sensors at work, With Dopler being the prefered by me, but not purchasing agents LOL
