Product details

The H2Flow Controls FlowVis FV-25 is a valve body with a built in check valve for 2-1/2 in. schedule 40 PVC, and it reads flow directly on a scale marked in GPM. One fitting gives you the flow reading and the non-return function that the pad needed anyway.

Why it goes in almost anywhere

Most flow meters demand long runs of straight pipe upstream and downstream, which is exactly what an existing equipment pad does not have. FlowVis can be installed with little to zero straight pipe and still holds 98.1% accuracy or better across the range, and it can be mounted horizontally, vertically or even upside down. That is what makes it a retrofit rather than a replumb.

Reading and upgrading

The scale is clear and needs no calibration out of the box. Models run from 1-1/2 in. up to 8 in. plus metric sizes, and the FV-D digital upgrade can be added to any FlowVis body later if you want the number logged instead of read by eye. FlowVis is manufactured in the USA.

Questions and answers

What people ask about this product, answered by our pool techs.

What pipe does the FV-25 fit?
2-1/2 in. schedule 40 PVC. FlowVis models cover 1-1/2 in. through 8 in. plus metric DN80 to DN200, so match the body to the pipe you have.
Does it replace my check valve?
It can. The 1-1/2 in., 2 in. and 2-1/2 in. FlowVis models double as a check valve, so the FV-25 does both jobs in one fitting.
Does it need straight pipe before and after it?
No. FlowVis can be installed with little to zero straight pipe with no effect on accuracy, which is what makes it easy to retrofit into a crowded equipment pad.
Do I have to calibrate it?
No. It installs and reads with no calibration. If you later want a digital readout, the FV-D upgrade fits any FlowVis model.
