FLOWVIS Retrofit Kit For Existing 7305 2" Jandy Check Valve - FVJ-R

FlowVis® is a revolutionary, patented solution for accurate and reliable flow rate measurement in freshwater applications such as swimming pools, spas, fountains, water features, irrigation systems, well water and solar systems.  

FlowVis® is the most advanced, affordable, and reliable precision flow meter designed specifically for pools, spas, fountains, and water features. Ingenious in concept and flawless in operation, FlowVis® is a revolution in reliable flow measurement!

A FlowVis® model also exists for Flotation Tanks and where the Specific Gravity has been raised to 1.25 by adding Epsom Salts. Using a design that is based on 'mass flow' principles, the FlowVis® provides many benefits that include:

• Ease of installation without the need to have 15x of 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
• Combined Flow Meter and Check Valve in all models except FV-C-S, FV-C-Saline, FV-3, FV-L-DN80, FV-4 and FV-L-DN100
• Installation flexibility; installs horizontally, vertically, or even upside-down
• Can be installed right next to other plumbing fittings such as elbows with no effect on accuracy
• ‰¥97.9% across the entire model range
• NSF 50 Level 1 for eight different FlowVis® models
• Doubles as a check valve (1.5", 2", 2.5" models)
• Clear, easy-to-read scale in GPM or optional LPM with key velocity points (FPS)
• Installs quickly and easily with no calibration required
• Manufactured in the USA
• 15-year design life, 3-year warranty
• Models available for Metric pipe sizes from DN40 to DN100
• The industry's most respected and reliable flow meter

As flow increases, the check valve or safety flapper moves forward toward its fully open position. The flapper's angular position is directly related to flow rate through the valve body/tee. A calibrated scale on the valve's lid provides a highly accurate reading of the flow rate.
