Flowvis Flow Meter, Retrofit Kit For Jandy Check Valve 2-2.5, FVJ-R, GPM, Model: , Home/Garden & Outdoor Store

Works exactly as you would expect and want. It fits perfect in the Jandy check valve I had bought for my system. I replaced two old pumps with a new variable speed pump and I use this flow meter to accurately set the speed of my pump. Great quality and overall great product. I love it and recommend it to anyone who wants a cool flow meter in their system. Thanks.
