More than a flow meter

Badge for Pool and Spa News 2021, listing Top 50 Products.

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.
