FlowVis Flow Meter
FlowVis is the most advanced, affordable, and reliable precision Flow Meter designed specifically for pools, spas, fountains, and water features. But FlowVis is more than just a flow meter; its also a fully functioning check valve! Ingenious in concept and flawless in operation, FlowVis is revolutionizing the way pool pumps operate.

FlowVis has undergone exhaustive testing and calibration to ensure long life, accuracy, and repeatability. No other Flow Meter at this price point comes remotely close to its +/- 2% accuracy.*

FlowVis is more than a Flow Meter; it is also a fully functioning Check Valve.

*Accuracy: +/- 2 GPM from 0 to 100 GPM


FlowVis is available in two configurations:

  1. A retrofit kit that installs to a pre-existing Jandy or Praher 2" x 2.5" Check Valve assembly
  2. A complete pre-assembled Check Valve assembly with FlowVis

Unlike other Flow Meters, the position in which FlowVis is installed (horizontal, vertical, or relative to elbows and tees), has only a minimal effect on accuracy.

What makes FlowVis different?

Pool installers, owners, and operators finally have a Flow Meter that they can rely on. Accuracy, reliability, and longevity are key among a list of unique features that include:

  • Combined functionality of Flow Meter and Check Valve
  • Accuracy of +/- 2%
  • Installation flexibility - far less space required than other flow meters.
  • Clear, easy to read scale
  • Installs in minutes

Built to Last

FlowVis is built to last. Its robust, yet unobtrusive design means that unlike competing Flow Meters, FlowVis wont get kicked, tripped over, or broken. Infact, were so confident in the durability of FlowVis that the product has a 5-year warranty on breakage!

Unlike Pitot tube / Rotameter style devices, FlowVis will not stick, bounce, or provide inaccurate readings of flow. There are no saddle clamps to corrode, flat rubber seals to deteriorate, or small holes to become blocked.
