We use a Rosemount magnetic flow meter in the fire pump test lines. It
installs in the line betwen two flanges so is not like a flow switch.
There are electronics in a separate panel. They are simple and have
basically no maintenance, although we did have to replace the electronics a
few years ago to the tune of about $6000. The original quit working and
was obsolete after 10 years. That's they way it is with electronic
equipment. They are accurate. We have flow tested it versus pitot
readings and it is pretty close.
We use it for gpm and I suppose you want it for gallonage. It will
probably total it up. Suggest calling the vendor for details. I am not
plugging this brand, just the only one we have any experience with.

Anyone have a lead on a flow meter that is simple to install and maintain
and accurate? Cheap would be nice but that might be asking too much.
Thinking something that goes on like a flow switch. To be honest I don't
think I've actually ever seen a flow meter. This would be in the drain
piping so no fears of fowling up the sprinkler side. I imagine where water
is limited you don't waste water for silly testing if you can recirculate.
You folks might have some more experience than here where water is
plentiful. Useless tidbit - MN has more shore line than CA, HI and FL
combined.
