Ingenious in concept and flawless in operation, FlowVis® flow meters have been revolutionizing the way flow is measured in pool and spa applications since their inception in 2012. With unrivaled accuracy, greater installation flexibility, and more NSF 50 certified models than any other brand, it’s easy to see why FlowVis® is the flow meter of choice for pool and spa professionals everywhere. FlowVis® is so much more than just a highly accurate flow meter. Models for 1.5” (DN40), 2” (DN50), and 2.5” (DN65) also provide the user with the benefit of check valve functionality. Additionally, models for 1.5” - 8” feature a readout of velocity in feet per second. These are just a couple of examples of why FlowVis has earned multiple awards such as Pool & Spa News Top 50 Products of 2021.
