8.1 General Installation Guidance
IMPORTANT INSTALLATION NOTE:
Before installing the FlowVis,
please refer to the preceding section regarding chlorine feeders.
Installation of FlowVis
®
should be in accordance with the following
instructions.
Normal plumbing procedures such as cleaning, priming and gluing of fixtures
should be followed in order to avoid leaks. If you are not familiar with plumbing
procedures, it is recommended that you employ the skills of a qualified plumber.
Unlike other flow meters, the majority of FlowVis
®
models are not affected by
flow stream disturbances caused by its proximity to pumps, elbows, tees, valves,
etc. FlowVis
®
can be installed either horizontally or vertically. Straight pipe
requirements are addressed in the table on page 19.
Pay particular attention to the system’s direction of flow and make sure that
the arrow on the lid of the FlowVis
®
is pointing in the correct direction. For
the FV-3, FV-3-L, FV-4, FV-4-L, FV-6, FV-6-L, FV-8 and FV-8-L versions, the
Tee / Saddle-clamp will feature an additional arrow label. In the event that the
FlowVis
®
is inadvertently installed into the plumbing in the wrong direction,
simply remove the (8) screws holding the lid in place and rotate the entire lid
assembly by 180
°
.
IMPORTANT NOTES:
a.
For all models 2.5” and smaller, always remove the FlowVis lid assembly
prior to gluing in the valve body.
b.
When selecting a physical location to install FlowVis, be sure to allow
accessibility to read the scale on the lid.
c.
Due to the possibility of excessive turbulence, models FV-3, FV-3-L, FV-4,
FV-4-L, FV-6, FV-6-L, FV-8 and FV-8-L should not be installed directly after
the pump.
d.
FlowVis models are designed for the specific pipe Schedule stated at the
bottom of the flow scale label. While it is important to comply with the
specific Schedule of pipe, the accuracy stated within this manual can be
maintained if a short length (3-6 inches / 75-150mm), of the correct pipe
