Very nice write up. Clear and easy to follow.

I also looked at using a turbine to sense flow. They are very low cost and generate a nice pulse. However, I felt that they would not be accurate enough, especially at low flow rates. At high rates, they also become inaccurate.

The Badger Model 25 is a very common water meter used by water departments and has been around for a long time. I compared it to the city's water meter and found that each revolution of its "nutating" disk equals 0.028 gallons. If it wasn't accurate, there would be law suits. The big down side of using this meter is the adapter I had to build in order to pick up the disk rotation and turn it into a pulse.
