Also I need two more post so I can answer PMs. I will just put the information here I hope you see it Ron. He had a question on how I monitor flow to my geo.

I use a raspberry Pi, a flow meter with a 1 gallon pulse output and some Python code to monitor it.

The python code uses an interrupt each time it records a pulse from the meter. The interrupt triggers code that calculates the time since the last pulse and from that I can calculate gpm since I know the time it took for 1 gallon to flow through the meter.

I have a 1/2" flow meter now. If I knew then what I know now I would have bought a 3/4". Since then I found a cheaper version:

Master Meter Flexible Axis Water Meter available at Flows.com!

I own the 1/2" model here:

DLJ Water Meter

I will probably buy a 3/4" next and move the 1/2" to a smaller project.

If you got any questions or need help let me know.
