FlowVis® is a revolutionary, patented solution for accurate and reliable fl ow rate measurement in fresh water applications such as swimming pools, spas, fountains, water features, irrigation systems, well water and solar systems. A FlowVis® model also exists for Flotation Tanks and where the Specifi c Gravity has been raised to 1.25 by adding Epsom Salts. Using a design that is based on 'mass fl ow' principles, the FlowVis® provides many benefi ts that include:
- Ease of installation without the need to have 15x of straight pipe
- Installation fl exibility that allows orientation in any position, e.g., horizontal, vertical or even upside-down
- Long life without sticking fl oats 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.
As fl ow increases, the check valve or safety fl apper moves forward toward its fully open position. The fl apper's angular position is directly related to fl ow rate through the valve body / tee. A calibrated scale on the valve's lid provides a highly accurate reading of the fl ow rate.
