DESCRIPTION
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, and
solar systems.
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.
CONCEPT
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.
