Flow Meter/Check Valve, FlowVis, 1-1/2”s

This works like a champ. Very easy to install and now I can easily monitor my flow rate of my new variable speed pump.

I have read that a swimming pool with 1.5" fittings should have a maximum flow of not more than 55 gallons per minute. But the Flowvis, specifically for 1.5" fittings, has a scale that registers to 110 gallons. As the scale is closer together at the lower end expanding as the scale rises it will be difficult to gauge the exact reading - especially as I anticipate operating in the range of 20 to 40 gallons per minute. Had the maximum been set at 60 gpm then this would not have been (or less of) a problem.

Perfect !
