9.0 OPERATION
The FlowVis® is factory-calibrated to
be extremely accurate across its full
operating range. Any ‘inaccuracy’ is
related to the angle in which the scale
is read. To avoid so-called ‘parallax
error’, it is important to position your
eye so that you are looking squarely
at the tip of the indicator arm. To
achieve this, simply move your head so
that you just lose sight of the vertical
leading edge of the red arm.
NOTE: Slowly move your head in
this direction to the point where the
leading edge of the indicating arm is
not visible.
