DESCRIPTION
FlowVis® is a revolutionary, patented solution for accurate and
reliable flow rate measurement in fresh water applications
such as swimming pools, spas, fountains, water features,
irrigation systems, well water and solar systems.
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 for DN40 and
DN50/65.
CONCEPT
As flow increases, the 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.
