The FlowVis is a revolutionary, affordable, and highly accurate flow meter. The best part is that the FlowVis™ is more than a flow meter; it is also a fully functioning check valve. Simply attach the retrofit FlowVis™ to your existing Jandy check valve and see your flow rate. A specifically designed calibration spring, indicating arm, and an extended height valve body lid constitute the fundamentals of the FlowVis design concept.
The FlowVis™ is a revolution in reliable flow measurement. It is the most advanced, affordable, and reliable precision flow meter designed specifically for pools, spas, fountains, and water features.
