FlowVis Complete Flow Meter with GPM Scale

FlowVis® shows actual water flow in gallons per minute, giving homeowners and pool professionals a measured basis for setting pump speed and checking equipment flow requirements. When adjusting a variable-speed pump, you can see the flow delivered at each setting and use that reading to assess whether circulation meets the equipment’s requirements. The easy-to-read scale also makes changes in flow visible during routine checks.

Available for 1.5 in., 2 in. and 2.5 in. pipe, these NSF 50 Level 1-certified models combine flow measurement, velocity indication and check-valve functionality in one unit. Installation horizontally, vertically or upside down, with little-to-no straight pipe required under the installation guidance, makes FlowVis practical for crowded equipment pads. No calibration is required, and an optional FlowVis Digital upgrade adds electronic monitoring.
