Chris- Look into Fire Research on Long Island, NY. http://www.fireresearch.com/ They make all sorts of Fire Department equipment but I bought their portable digital flowmeters (2 1/2" insight). I have 5 of them now and I use them for standpipe testing, fire and hydrant testing (especially when it's below freezing) and flushing. They are fabulous. You can calibrate them against a pitot, hosemonster or each other. I've never had to adjust them much more than 5-10 GPM at 250-1000 through a single one.
Tom GRS 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. John Hoffman, P.E. 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.
