H2flow FLOWVIS User Manual

1.0 DESCRIPTION
FlowVis® is a revolutionary Patent Pending product that converts a standard Check
Valve into a Flow Meter and Check Valve.
The product is currently available in two formats:
a) Retro t to install to an existing Jandy® (7305) 2” by 21/2” Check Valve body -
FV-J.
b) A complete Check Valve body assembled with FlowVis® - FV-C.
c) A complete Check Valve body assembled with FlowVis® and a safety  apper, as
described in section 6 of this manual.
The Retro t kit comprises a fully assembled FlowVis® lid, calibrated spring, pin, indicator
arm, ‘O’-ring and calibrated scale. Installation simply requires the removal of the eight
screws securing the existing lid, installing the new ‘O’-ring and securing the FlowVis®
with the original eight screws.
2.0 CONCEPT
As  ow increases, the check valve  apper extends towards its fully open position. The
angular position of the  apper is determined by the  ow through the valve body. A
calibrated scale on the valve lid provides an accurate reading of  ow.
