FlowVis® is over 95% accurate across the entire product range, making it the most accurate flow meter designed specifically for pools, spas, fountains, and water features.

FlowVis® is available as both a complete pre-assembled unit for 1.5", 2", 2.5", 3", & 4" and also as a retrofit kit that installs to a pre-existing Jandy® or Praher® 1.5", 2", or 2.5" check valve assembly.

FlowVIs® can be installed horizontally, vertically, or even upside-down, and within any proximity to other fittings with no effect on accuracy.
