FlowVis is a revolutionary, patented solution for accurate and reliable flow and velocity rate measurement in fresh water applications such as swimming pools, spas, fountains, water features, irrigation systems, ground water applications, well water and solar systems. As flow increases, the flapper moves forward toward its fully open position. The flapper’s angular position is directly related to the flow rate through the valve body/tee/pipe. A calibrated scale on the valve’s lid provides a highly accurate reading of the flow rate and velocity.

• Ease of installation with zero to minimal straight pipe
• Installation flexibility that allows orientation in any position, e.g., horizontal, vertical or even upside-down
• Long life without sticking floats or paddle wheels
• For use with external motor driven pumps only
